Getting Acquainted — Read This First! k About this User’s Guide u Model-specific Function and Screen Differences This User’s Guide covers multiple different calculator models. Note that some of the functions described here may not be available on all of the models covered by this User’s Guide. All of the screen shots in this User’s Guide show the fx-9860GIII screen, and the appearance of the screens of other models may be slightly different.
u Function Keys and Menus • Many of the operations performed by this calculator can be executed by pressing function keys 1 through 6. The operation assigned to each function key changes according to the mode the calculator is in, and current operation assignments are indicated by function menus that appear at the bottom of the display. • This User’s Guide shows the current operation assigned to a function key in parentheses following the key cap for that key.
Chapter 1 Basic Operation 1.
k Key Markings Many of the calculator’s keys are used to perform more than one function. The functions marked on the keyboard are color coded to help you find the one you need quickly and easily. Function Key Operation 1 log l 2 10x !l 3 B al The following describes the color coding used for key markings. Color • Key Operation Yellow Press ! and then the key to perform the marked function. Red Press a and then the key to perform the marked function.
3. Press w to display the initial screen of the mode whose icon you selected. Here we will enter the STAT mode. • You can also enter a mode without highlighting an icon in the Main Menu by inputting the number or letter marked in the lower right corner of the icon. • Use only the procedures described above to enter a mode. If you use any other procedure, you may end up in a mode that is different than the one you thought you selected. The following explains the meaning of each icon.
Icon Mode Name TVM* Description (Financial) Use this mode to perform financial calculations and to draw cash flow and other types of graphs. E-CON3* Use this mode to control the optionally available Data Logger. LINK Use this mode to transfer memory contents or back-up data to another unit or PC. MEMORY Use this mode to manage data stored in memory. SYSTEM Use this mode to initialize memory, adjust contrast, and to make other system settings.
u How to interpret exponential format 1.2E+12 indicates that the result is equivalent to 1.2 × 1012. This means that you should move the decimal point in 1.2 twelve places to the right, because the exponent is positive. This results in the value 1,200,000,000,000. 1.2E–03 indicates that the result is equivalent to 1.2 × 10–3. This means that you should move the decimal point in 1.2 three places to the left, because the exponent is negative. This results in the value 0.0012.
k Editing Calculations Use the d and e keys to move the cursor to the position you want to change, and then perform one of the operations described below. After you edit the calculation, you can execute it by pressing w. Or you can use e to move to the end of the calculation and input more. • You can select either insert or overwrite for input*1. With overwrite, text you input replaces the text at the current cursor location. You can toggle between insert and overwrite by performing the operation: !D(INS).
k Using Replay Memory The last calculation performed is always stored into replay memory. You can recall the contents of the replay memory by pressing d or e. If you press e, the calculation appears with the cursor at the beginning. Pressing d causes the calculation to appear with the cursor at the end. You can make changes in the calculation as you wish and then execute it again. • Replay memory is enabled in the Linear input/output mode only.
w Press J. Cursor is positioned automatically at the location of the cause of the error. Make necessary changes. db Execute again. w k Using the Clipboard for Copy and Paste You can copy (or cut) a function, command, or other input to the clipboard, and then paste the clipboard contents at another location. • The procedures described here all use the Linear input/output mode.
2. Use the cursor keys to move the cursor and highlight the range of text you want to cut. 3. Press 2(CUT) to cut the highlighted text to the clipboard. Cutting causes the original characters to be deleted. u Pasting Text Move the cursor to the location where you want to paste the text, and then press !j(PASTE). The contents of the clipboard are pasted at the cursor position. A !j(PASTE) k Catalog Function The Catalog is an alphabetic list of all the commands available on this calculator*.
4. Input the first letter of the command you want to input. This will display the first command that starts with that letter. • fx-9860GIII, fx-9750GIII: You can input up to eight letters to search for a command (only when “1:All” is selected in the category list). For details, see “Searching for a Command (fx-9860GIII/fx-9750GIII only)” (page 1-10). 5. Use the cursor keys (f, c) to highlight the command you want to input, and then press 1(INPUT) or w.
u Using the Command History (fx-9860GIII/fx-9750GIII only) The calculator maintains a history of the last six commands you input. 1. Display one of the command lists. 2. Press 5(HIST). • This displays the command history. 3. Use f and c to move the highlighting to the command you want to input and then press 1(INPUT) or w. u QR Code Function (fx-9860GIII/fx-9750GIII only) • You can use the QR Code function to access the online manual that covers commands.
4. Press J to close the QR Code screen. • To exit the Catalog function, press A or !J. 4. Using the Math Input/Output Mode Important! • The fx-7400GIII is not equipped with a Math input/output mode. Selecting “Math” for the “Input/Output” mode setting on the Setup screen (page 1-31) turns on the Math input/output mode, which allows natural input and display of certain functions, just as they appear in your textbook. • The operations in this section all are performed in the Math input/output mode.

u Variable Specifications There are two methods you can use to specify value for the variable x when generating a numeric table. • Table range method With this method, you specify the conditions for the change in value of the variable. • List With this method, the data in the list you specify is substituted for the x-variable to generate a number table.
Press 6(TABL) to generate a number table using the functions you selected. The value of variable x changes according to the range or the contents of the list you specified. The example screen shown here shows the results based on the contents of List 6 (–3, –2, –1, 0, 1, 2, 3). Each cell can contain up to six digits, including negative sign.
• If you try to replace a value with an illegal operation (such as division by zero), an error occurs and the original value remains unchanged. • You cannot directly change any values in the other (non-x) columns of the table. k Copying a Table Column to a List A simple operation lets you copy the contents of a numeric table column into a list. Use d and e to move the cursor to the column you want to copy. The cursor can be in any row.

Chapter 6 Statistical Graphs and Calculations Important! This chapter contains a number of graph screen shots. In each case, new data values were input in order to highlight the particular characteristics of the graph being drawn. Note that when you try to draw a similar graph, the unit uses data values that you have input using the List function. Because of this, the graphs that appear on the screen when you perform a graphing operation will probably differ somewhat from those shown in this manual. 1.
• List The initial default statistical data is List 1 for single-variable data, and List 1 and List 2 for paired-variable data. You can specify which statistical data list you want to use for x-data and y-data. • Frequency This setting specifies a list that contains frequency data. In statistics, “frequency” means the number of times a data item (or set of data items) occurs.
When “Pie” (pie graph) is selected as the Graph Type: • Data (Specifies the list to be used as graph data.) • {LIST} ... {List 1 to List 26} • Display (pie graph value display setting) • {%}/{Data} ... For each data element {display as percentage}/{display as value} • % Sto Mem (Specifies storage of percentage values to a list.) • {None}/{List} ...
Pie, 1-Sample Z Test, 2-Sample Z Test, 1-Prop Z Test, 2-Prop Z Test, 1-Sample t Test, 2Sample t Test, χ2 GOF Test, χ2 2-way Test, 2-Sample F Test (x-axis only disregarded). • The default setting automatically uses List 1 data as x-axis (horizontal) values and List 2 data as y-axis (vertical) values. Each set of x/y data is a point on the scatter diagram. 2. Calculating and Graphing Single-Variable Statistical Data Single-variable data is data with only a single variable.
⇒ w(DRAW) The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. k Med-box Graph This type of graph lets you see how a large number of data items are grouped within specific ranges. A box minX encloses all the data in an area from the first quartile (Q1) to the third quartile (Q3), with a line drawn at the median (Med). Lines (called whiskers) extend from either end of the box up to the minimum (minX) and maximum (maxX) of the data.
k Normal Distribution Curve The normal distribution curve is graphed using the normal distribution function. XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input. 1 is specified for Freq when frequency is not specified. k Broken Line Graph Lines connect center points of a histogram bar. XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input.
• Press 6(DRAW) to return to the original single-variable statistical graph. • When Mod has multiple solutions, they are all displayed. • You can use the Setup screen’s “Q1Q3 Type” setting to select either “Std” (standard calculation) or “OnData” (French calculation) for the Q1 and Q3 calculation mode. For details about calculation methods while “Std” or “OnData” is selected, see “Calculation Methods for the Std and OnData Settings” below.
Center Point 1 2 3 Center Point 4 5 6 7 8 9 Median 2+3 = Q1 2 7+8 = Q3 2 • When Frequency includes decimal fraction values The Q1, Q3 and Med values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 0.25 and nearest to 0.25} When the cumulative frequency ratio for some data value is exactly 0.25, Q1 is the average of that data value and the next data value.
u OnData The Q1, Q3 and Med values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 0.25 and nearest to 0.25} Q3 = {value of element whose cumulative frequency ratio is greater than 0.75 and nearest to 0.75} The following shows an actual example of the above. (Number of Elements: 10) Data Value Frequency Cumulative Frequency Cumulative Frequency Ratio 1 1 1 1/10 = 0.1 2 1 2 2/10 = 0.2 3 2 4 4/10 = 0.4 4 3 7 7/10 = 0.

k Power Regression Graph Power regression expresses y as a proportion of the power of x. The standard power regression formula is y = a × xb, so if we take the logarithm of both sides we get In y = In a + b × In x. Next, if we say X = In x, Y = In y, and A = In a, the formula corresponds to linear regression formula Y = A + bX. 1(CALC)6(g)4(Pwr) 6(DRAW) The following is the power regression model formula. y = a·xb a .............. regression coefficient b ..............
While the statistical data list is on the display, recall the Setup screen to specify a LIST (“List 1” through “List 26”) for “Resid List”. Calculated residual data is stored in the specified list. The vertical distance from the plots to the regression model will be stored in the list. Plots that are higher than the regression model are positive, while those that are lower are negative. Residual calculation can be performed and saved for all regression models.

9. Program Library • Be sure to check how many bytes of unused memory are remaining before attempting to perform any programming. Program Name Prime Factorization Description This program continually divides a natural number by factors until all its prime factors are produced. Purpose This program accepts input of natural number A, and divides it by B (2, 3, 5, 7....) to find the prime factors of A. • If a division operation does not produce a remainder, the result of the operation is assigned to A.
Program Name Ellipse Description This program displays a number table of the following values based on input of the foci of an ellipse, the sum of the distance between the loci and foci, and the pitch (step size) of X. Y1: Coordinate values of upper half of ellipse Y2: Coordinate values of lower half of ellipse Y3: Distances between right focus and loci Y4: Distances between left focus and loci Y5: Sum of Y3 and Y4 Next, the program plots the foci and values in Y1 and Y2.
Chapter 9 Spreadsheet The Spreadsheet application provides you with powerful, take-along-anywhere spreadsheet capabilities. All of the operations in this section are performed in the S • SHT mode. Important! • The fx-7400GIII is not equipped with the S • SHT mode. 1. Spreadsheet Basics and the Function Menu Selecting S • SHT on the Main Menu will display a spreadsheet screen. Entering the S • SHT mode automatically creates a new spreadsheet file named “SHEET”.
• {DEL} ... Displays the following DEL (delete) submenu. • {ROW}/{COL}/{ALL} • {INS} ... Displays the following INS (insert) submenu. • {ROW}/{COL} • {CLR} ... Clears the content from a selected range of cells. • {GRPH} ... Displays the following GRPH menu. (Same as in the STAT mode.) • {GPH1}/{GPH2}/{GPH3}/{SEL}/{SET} • {CALC} ... Displays the following CALC (statistical calculation) menu. (Same as in the STAT mode.) • {1VAR}/{2VAR}/{REG}/{SET} • {STO} ... Displays the following STO (store) submenu.
u To open a file 1. Press 1(FILE)2(OPEN). 2. On the file list that appears, use f and c to select the file you want and then press w. u Auto Save In the S • SHT mode, Auto Save saves the currently open file automatically whenever you edit it. This means you do not need to perform any manual save operation. u To save a file under a new name 1. Press 1(FILE)3(SV • AS). 2. On the dialog box that appears, enter up to eight characters for the new file name, and then press w.
Important! • All blank data in the CSV file is imported as a blank cell. • An error occurs if a CSV file contains even a single text string data item. • If the CSV file includes data that cannot be converted, an error message will appear showing the location in the CSV file (Example: row 2, column 3) where the data that cannot be converted is located. • Attempting to import a CSV file that has more than 26 columns or 999 rows will cause an “Invalid Data Size” error.
u Auto Calc Auto Calc is an S • SHT mode Setup item (page 1-34). When Auto Calc is enabled (On), all of the formulas in a spreadsheet are recalculated when the spreadsheet is opened or when any editing operation is performed. It should be noted, however, that recalculation can slow down the overall processing speed. When Auto Calc is disabled (Off), you need to execute recalculation manually as required. u To execute spreadsheet re-calculation manually Press 1(FILE)4(RECAL).
To select this: Do this: An entire column of cells. Move the cell cursor to row 1 of the column whose cells you want to select and then press f. Pressing f while the cell cursor is located at cell C1, for example, will select the entire column C (from C1 to C999). This will cause C1:C999 (which indicates the selected range) to appear in the edit box. All of the cells in the spreadsheet Press d while the entire column A is selected or press f while the entire row 1 is selected.
k Data (Constants, Text, Formula) Input Basics First let’s have a look at a few basic procedures that apply regardless of the type of data you are inputting. u To overwrite data currently in a cell with new data 1. Move the cell cursor to the cell where you want to input data. • If the cell you select already contains data, the following step will overwrite the existing data with new input. 2. Use the calculator’s keys to input data.
k Inputting a Constant (Value, Calculation Result, Number Sequence) into a Cell A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit).
• Performing the next step will input the number string automatically starting from the specified cell. If any cell that is within the range of cells where the number sequence values will be input already contains data, the existing data will be replaced with the number sequence values. 3. After inputting data for all the setting items, press 6(EXE) or the w key to start number sequence generation and input.
3. Copy the formula in cell C2 and copy it into cells C3 and C4. Move the cell cursor to cell C2 and then perform the following operation. 2(EDIT)2(COPY)c1(PASTE)c1(PASTE)J • For details about the copy and paste operations, see “Copying and Pasting Cell Contents” (page 9-11). k Inputting a Cell Reference Name Each cell on a spreadsheet has what is called a “reference name”, which is derived by combining its column name (A through Z) with its row name (1 through 999).
Absolute Reference Names If you want the row or the column, or both the row and the column parts of a cell reference name to remain the same to matter where you paste them, you need to create an absolute cell reference name. You do this by affixing a dollar sign ($) in front of the part of the cell reference name you want to remain unchanged.
k Cutting and Pasting Cell Contents You can use cut and paste to move the contents of one or more cells to another location. Cell contents (regardless of whether it includes relative or absolute cell name references) generally are unchanged by a cut and paste operation. ⇒ Cutting the formula =A1+5 in cell B1 and pasting it into cell B2. The A1 reference name is unchanged.
k Inputting the Same Formula into a Range of Cells Use the Fill command when you want to input the same formula into a specified range of cells. The rules governing relative and absolute cell name references are the same as those for copy and paste. When you need to input the same formula into cells B1, B2, and B3, for example, the Fill command lets you do so by inputting the formula once, into cell B1. Note the following about how the Fill command handles cell name references in this case.
k Sorting Constant Data Note that only constant data can be sorted. You can select multiple columns within a single line or multiple lines within a single column for sorting. u To sort constant data 1. Select a range of column cells in a single row or a range of row cells in a single column. • See “To select a range of cells” (page 9-6). • A Syntax ERROR message will appear if any of the cells in the range you select contain data other than constant data. 2.
• To insert columns Starting with the column immediately to the right of the column where you want the insert to be performed, select the same number of columns that you want to insert. Example: To insert three columns to the left of column B, you could select B2:D4, B10:D20, etc. 2. Press 4(INS). • This will enter insert standby. If you decide you want to cancel the insert operation at this time, press J. 3. Press 1(ROW) to insert the applicable number of rows or 2(COL) to insert columns.
Command Description CellMean( (Mean of Cells) Returns the mean value in a specified range of cells. Input Key Operation: 5(CEL)3(Mean) Syntax: CellMean(start cell:end cell[)] Example: =CellMean(A3:C5) Returns the mean value of the data in cell range A3:C5. CellMedian( (Median of Cells) Returns the median value in a specified range of cells. Input Key Operation: 5(CEL)4(Med) Syntax: CellMedian(start cell:end cell[)] Example: =CellMedian(A3:C5) Returns the median value of the data in cell range A3:C5.
4. Drawing Statistical Graphs, and Performing Statistical and Regression Calculations When you want to check the correlation between two sets of data (such as temperature and the price of some product), trends become easier to spot if you draw a graph that uses one set of data as the x-axis and the other set of data as the y-axis. With the spreadsheet you can input the values for each set of data and draw a scatter plot or other types of graphs.
u To configure statistical graph settings 1. Input the statistical calculation data into the spreadsheet and then select the range of cells you want to graph. • Actually, the above step is not necessary at this point. You also could configure settings first before inputting data and selecting the range of cells to be graphed. 2. Press 6(g)1(GRPH)6(SET). • This will display the general graph settings screen (StatGraph1 in this example).
• If you want to change the XCellRange, YCellRange, or Frequency setting, move the highlighting to the item you want to change and then input the cell range directly, or select 1(CELL) (2(CELL) for Frequency) and then edit the currently input range. When inputting a cell range manually, use 1(:) to enter a colon (:) between two cells that define the range. 4. After configuring the required settings, press J or w.
• The number of columns you select in step 1 will determine what information is input automatically on the statistical calculation data range specification screen. If you select this number of columns: This information will be input automatically: 1 1Var XCell and 2Var XCell 2 1Var Freq and 2Var YCell 3 2Var Freq • The following describes each of the setting items for this screen.
For information about this menu item: Refer to: {CALC} - {2VAR} “Paired-Variable Statistical Calculations” (page 6-16) {CALC} - {REG} “Regression Calculation” (page 6-17) {CALC} - {SET} “Using the Statistical Calculation Data Range Specification Screen” (page 9-19) 5. S • SHT Mode Memory You can use the calculator’s different types of memory (variables, list memory, file memory, matrix memory, vector memory) to store data, and recall data from a memory into the spreadsheet.
Important! The following describes what happens if you try to store data in memory when a cell does not contain any data, when a cell contains text, or when ERROR is displayed for a cell. • If you are assigning data to a variable, an error occurs. • If you are storing data in list memory, file memory, matrix memory, or vector memory, 0 is written into the applicable cell(s). u Example: To store column data in list memory 1. In a single column, select the range of cells you want to store in list memory.
Memory Type Vector Memory (Vct A ~ Vct Z) Recall Operation You can recall data from a specified vector memory to a range of cells in a single row or a single column. While the first cell of the range in a single row or single column is selected, press 6(g)4(RCL)4(VCT), and then specify the vector name on the screen that appears. u Example: To recall data from a matrix memory to a spreadsheet 1. On the spreadsheet, select the upper left cell of the range where you want the recalled data to be input. 2.
Chapter 10 eActivity You can use the e • ACT mode to input data into an eActivity file. You can input text and numeric expressions, and also paste data (like graphs, tables, etc.) from the calculator’s builtin applications as “strips”. eActivity files can be used by a teacher, for example, to create math problems or exercises that provide hints to solutions, for distribution to students. Students can use eActivity files to keep classroom notes, memos of problems and their solutions, etc.
The following explains the type of data you can input and edit in an eActivity file. Text line ................A text line can be used to input characters, numbers, and expressions as text. Calculation line......Use the calculation line to enter an executable calculation formula. The result will appear in the following line. Calculations are performed the same way as they are performed in the RUN • MAT mode, while natural input is enabled. Stop line ................
• {'MAT} ... Displays the Matrix Editor (page 10-7)/Vector Editor (page 10-7). • {'LIST} ... Displays the List Editor (page 10-7). • Menu when a Text Line is Selected • {TEXT} ... Changes the current line from a text line to a calculation line. • {CHAR} ... Displays a menu for inputting math symbols, special symbols, and characters of various languages. • {A↔a} ... Toggles between uppercase and lowercase input while alpha character input is enabled (by pressing the a key). • {MATH} ...
u To open a file Use f and c to highlight the file you want to open, and then press 1(OPEN) or w*. * If an error occurs, delete capture memory and clipboard data, or transfer the data to your computer. u To delete a file 1.

k Inputting into a Text Line Use a text line to input alphanumeric characters, expressions, etc. u Inputting characters and expressions as text 1. Move the cursor to a text line. • While the cursor is in a text line, “TEXT” will be displayed for the F3 function menu item. This indicates that text input is enabled. Text line cursor 3 key menu becomes “TEXT”. • “CALC” will be displayed for the F3 function menu item if the cursor is located in a calculation line.
k Inputting into a Calculation Line Inputting a calculation expression into an eActivity calculation line and pressing w will display the calculation result in the following line. Such a calculation line can be used in the same way as the RUN • MAT mode (page 1-3). A calculation line and its result make up one set. • Note that the word wrap function does not apply in the case of math lines.
u Matrix Calculations Using the Matrix Editor Selecting {'MAT} on the function menu displays the Matrix Editor. Matrix Editor operations and matrix calculations in the e • ACT mode are the fundamentally identical to those in the RUN • MAT mode. For details about the Matrix Editor and matrix calculation operations, see “Matrix Calculations” (page 2-38). Note, however, that e • ACT mode Matrix Editor operations and matrix calculations differ from those in the RUN • MAT mode as described below.
k Using Strips Strips are tools that let you embed built-in application data into an eActivity file. Only one built-in application screen can be associated with each strip, and the strip can store the data (graphs, etc.) produced by the screen. The table below shows the built-in application screens that can be inserted into strips. The “Strip Name” column shows the names included on the dialog box that appears when you press 2(STRP).
u To insert a strip 1. Move the cursor to the location where you want to insert the strip. 2. Press 2(STRP). • This will display a dialog box with a list if insertable strips. For information about the display names and data types that appear on this dialog box, see the “Strip Data Type Table” (page 10-8). 3. Use c and f to select the strip that corresponds to the type of data you want to insert. • In this example we will select “Graph” (GRAPH mode graph screen data). 4. Press w.
9. Press 6(DRAW). • This will graph the function you entered. 10. To return to the eActivity workspace screen, press !a('). • The data that is graphed in step 8 will be saved in the Graph strip. • The saved graph data is linked to this Graph strip only. It is independent of data for modes that are entered from the Main Menu. 11. Pressing w here again will display the graph screen, and draw the graph based on the data saved by the strip.
u To call an application from a strip Use c and f to select the strip whose application you want to call and then press w. • This will display the application screen that corresponds to the selected strip. If the strip already contains data, the application is called using the data that was last saved. • If you select a Conics Graph strip and press w without inputting any graph data, the Conics Editor screen appears in place of the Conics Graph screen.
(with OS Version 2.0 or later operating system) to save an eActivity file always will cause the extension “g2e” to be appended to the file name. • Saving a newly created file • Saving an existing file using the “save as” operation (1(FILE)2(SV-AS)) If you save an eActivity file using a calculator model covered by this manual to save a file with a file name extension “g1e” (a file transferred from an older version calculator), the file name extension will be determined according to the following rules.

u Precautions when Connecting • An hourglass figure may remain projected on the screen after you connect the calculator to a projector (or YP-100). Also, changing to another screen while a graph is being drawn or while a PRGM mode program is running could possibly result in the projected screen being different from the calculator screen. If this happens, performing some operation on the calculator will restore normal display.
Chapter 14 PYTHON (fx-9860GIII, fx-9750GIII only) The PYTHON mode provides a runtime environment for the Python programming language. You can use the PYTHON mode to create, save, edit, and run Python files. Important! • The PYTHON mode supports a version of MicroPython Version 1.9.4, which has been adapted to run on this calculator. Note that generally, MicroPython is different from the Python that runs on a computer.
k Flow from py File Creation to Running the File The example below explains the operation flow from creation of a new py file up to running it. Example: To create a py file that obtains the surface area and volume of a regular octahedron and to run it to calculate the surface area and volume when the length of one side is 10. The file name is OCTA. You can obtain the surface area (S) and volume (V) of a regular octahedron when the length of one side (A) is known using the formulas below.
3. Perform the key operations below to input each line of the py script. • You can use the PYTHON mode Catalog Function (page 14-9) for more efficient input of functions and commands. In the key operations below, text strings that are underlined and included in parentheses indicate function and command names input with the Catalog Function. Perform this key operation: To input this: !e(CATALOG)6(CTGY)d(math)((I)(import math) ww import math a5(A↔a)v(A)!.
k SHELL Screen Pressing 2(RUN) in step 4 of the procedure above starts up the PYTHON mode SHELL, which can be used for running py scripts. The screen that appears at this time is called the “SHELL screen”. The SHELL screen not only lets you run py scripts that have been saved as files, you can also directly input expressions and commands and execute them one line at a time. For details about SHELL, see “Using the SHELL” (page 14-13).
k Function Menu for Registering a Name for a New py File • {A↔a} … toggles between upper-case and lower-case input k Script Editor Screen Function Menu • {FILE} • {SAVE} … overwrites the currently open py file • {SV • AS} … saves the currently open py file under a different name • {RUN} ...
3. Inputting Text and Commands There are three ways to input text and commands in the PYTHON mode. • Using the keyboard to input alpha characters, symbols, and functions (See the procedure below.
Important! Among the text strings above that are input using key operations, log() and other functions that are followed by parentheses, e (base of a natural logarithm), and pi are math module functions. To use these functions, you first need to import the math module.* For details, see “Command Categories” (page 14-10) and “Operation Example: To use math module functions” (page 14-12). * If you use import instead of from to input the module, you need to append “math.” before each function you use.
k Using the Function Menu to Input Commands (Conditional Branches or Loops) as Statement Blocks From the script editor screen, you can use the function menu {COM} menu to input conditional branch command and loop command statement blocks.
u Example: To input an if...else statement 1. On the script editor screen, move the cursor to the line where you want to input the statement block and then press 6(g)1(COM)2(ifelse). • This inputs the if...else statement block, with the cursor positioned for input of the if condition. • Lines 2 and 4 are indented two spaces automatically. k Inputting a Command from the Catalog (Catalog Function) The catalog is a list of functions and commands.
4. Use f and c to select the command you want to input. 5. After selecting the command you want to input, press 1(INPUT) or w. • When you enter the PYTHON mode and display the catalog, the command that was selected the last time you displayed the catalog will appear first. Command Categories The contents of each category of the PYTHON mode catalog are described in the table below. Category Name Description All Shows a list of all functions and commands included in the PYTHON mode catalog.
k Using Modules (import) In the PYTHON mode, you can use Python built-in functions, and math module and random module functions. However, to use a function contained in a module you have to first import (import) the module. Description import Syntax import Imports the module (py file) specified by . from import ¼ Imports all of the elements* included in the module specified by .
u Operation Example: To use math module functions 1. From the file list screen, press 4(SHELL). 2. Press !e(CATALOG) to display the catalog. 3. Press 6(CTGY) to display the category screen, and then press d(math). 4. Perform the key operation sequence below. h(M)w (Inputs “math.”) !e(CATALOG)I(C)w (Inputs “ceil()”) 5. Press b.cw. • The math module is not imported, so the “ceil()” math module function causes an error. 6.
4. Using the SHELL The SHELL screen provides an interactive command line that can be used input expressions and commands, and output their results. You can directly input an expression or command on the SHELL screen and execute it to obtain a result. Running a py file will display its result on the SHELL screen.
u To execute a command from the SHELL screen See “Inputting a Command Directly on the SHELL Screen and Executing It” (page 14-15). u To scroll the SHELL screen vertically (to display history lines) Press f or c. The currently selected history line is the one that is highlighted. u To scroll one line of the SHELL screen (history line or prompt line) horizontally 1. Use f and c to move the highlighting to the line you want to scroll. 2. Press d or e.
k Inputting a Command Directly on the SHELL Screen and Executing It You can input a single-line expression or command into the SHELL screen prompt line and execute it. The example operations below all start with the SHELL screen already displayed. u Operation Example 1: To perform simple arithmetic operations (2+3) × 102 = 500 (c+d)*baxw 2+3 × (4+5) = 29 c+d*(e+f)w Note the important points below. • Use the - key, not the - key, to input a minus sign.
u input Operation in the PYTHON mode input is a built-in Python function that accepts user input while a py script is running. input Syntax input([prompt text string]) Description While a py script is running, input writes the [prompt text string] of the argument into the SHELL result output line, and stands by for user input. A string variable name or a character string enclosed in double quotation marks (”) or single quotation marks (’) can be specified for the [prompt text string].
• If the SHELL is restarted by running a py script from the file list screen or script editor screen, the SHELL will be initialized before the py script is run. Because of this, the SHELL screen will appear as shown in the screen shot below. “¼ SHELL Initialized ¼” message py script execution command py script execution result Prompt line 5.
u To search for text on the script editor screen 1. From the script editor screen, press 6(g)4(SRC). 2. On the screen that appears, enter the character string you want to search for and then press w. • This starts searching from the top of the py script, and moves the cursor to the left of the first character of the first matching character string that is found. If there is no matching character string found, the message “Not Found” will appear. If this happens, press J.
u Using Error Messages for Debugging If an error message appears on the SHELL screen when you run a py file, perform the steps below. 1. Use f to move the highlighting to the error message line, and then use d and e to check the details of the error message. 2. Press J. • This returns to the screen from which the py file was run (script editor screen or file list screen). Open the py file where the error occurred and check the contents of the line for which an error message was displayed.
6. File Management (Searching For and Deleting Files) You can use the file list screen to search for saved py files by their file names, and to delete files. • py files you create in the PYTHON mode are stored in the calculator’s storage memory. • In addition to file operations described in this section, you can also use Memory Manager to create folders and perform other folder operations. See “Chapter 11 Memory Manager” for more information. u To search for a py file by its file name 1.
7. File Compatibility py files can be shared between your calculator and a computer. A py file created with the calculator can be transferred to a computer for editing with a text editor or other software. A py file created on a computer can be transferred to and run on the calculator. • py files you create in the PYTHON mode are stored in the calculator’s storage memory (with file name extension py).
u File Content Display and Editing Opening a py file that satisfies conditions (A) and (B) below in the PYTHON mode will produce a normal display of all of the file contents. A py file that shows contents can be displayed normally and edited in the PYTHON mode. (A) py file written in ASCII characters only and saved using UTF-8 or other ASCII-compatible codes • If a file saved with character codes that are not compatible with ASCII, none of its contents will be displayed if you open it in the PYTHON mode.
8. Sample Scripts Sample 1: Conditional Branching Purpose With conditional branching a condition is evaluated and then processing follows one of multiple paths in accordance with the evaluation result. The example below is for a simple “if... else...” statement. Description a=int(input("a=")) Accepts user input while the py script is running. Input values are converted to integers and define variable a. if a<5: If the variable a is less than 5, print("a<5") else: outputs the text string a<5.
Sample 2: Importing a Module Purpose import imports a module and makes it possible to run the functions defined within it. Use the syntax below to execute function within the module. . Description import math Imports the math module and makes it possible to run the function defined by it. P=math.pi Defines variable P as pi, which is defined in the math module. print(P) Outputs the value stored in variable P.
Description def f(x,y,z): if x>0: t=x+y+z else: t=x-y-z return(t) Defines a user-defined function with function name f, and arguments x, y, and z. If variable x is greater than 0, defines variable t as the execution result of x+y+z. Otherwise (if variable x is 0 or less), defines variable t as the execution result of x-y-z. Makes variable t the return value. Running this py script as a standalone script will only define the user defined function.
Execution Result Important! • To import py files into other py file or files, all of the files must be in the same directory (folder). • py files that can be imported with the SHELL screen are those described below. - If the SHELL is started up by a file list screen operation,* importable files are py files in the directory displayed on the file list screen.
