1-1 Before Starting Calculations... Before performing a calculation for the first time, you should use the set up screen to specify the angle unit and display format. k Setting the Angle Unit (Angle) 1. Display the set up screen and use the f and c keys to highlight “Angle”. 2. Press the function key for the angle unit you want to specify. • {Deg}/{Rad}/{Gra} ... {degrees}/{radians}/{grads} 3. Press J to return to the screen that was on the display when you started the procedure.
Before Starting Calculations... 1-1 u To specify the number of significant digits (Sci) Example To specify three significant digits 2 (Sci) 4 (3) Press the function key that corresponds to the number of significant digits you want to specify (n = 0 to 9). • Displayed values are rounded off to the number of significant digits you specify. • Specifying 0 makes the number of significant digits 10.
1-1 Before Starting Calculations... k Inputting Calculations When you are ready to input a calculation, first press A to clear the display. Next, input your calculation formulas exactly as they are written, from left to right, and press w to obtain the result.
Before Starting Calculations... 1-1 ! Relational operator =, G, >, <, ≥, ≤ @ And (logical operator), and (bitwise operator) # Or (logical operator), or (bitwise operator), xor, xnor • When functions with the same priority are used in series, execution is performed from right to left. exIn 120 → ex{In( 120 )} Otherwise, execution is from left to right. • Compound functions are executed from right to left. • Anything contained within parentheses receives highest priority. Example 2 + 3 × (log sin2π2 + 6.
1-1 Before Starting Calculations... k Stacks The unit employs memory blocks, called stacks, for storage of low priority values and commands. There is a 10-level numeric value stack, a 26-level command stack, and a 10-level program subroutine stack. An error occurs if you perform a calculation so complex that it exceeds the capacity of available numeric value stack or command stack space, or if execution of a program subroutine exceeds the capacity of the subroutine stack.
Before Starting Calculations... 1-1 k Overflow and Errors Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed. The following events cause an error message to appear on the display. • When any result, whether intermediate or final, or any value in memory exceeds ±9.999999999 × 1099 (Ma ERROR). P.
1-1 Before Starting Calculations... k Graphic Display and Text Display The unit uses both a graphic display and a text display. The graphic display is used for graphics, while the text display is used for calculations and instructions. The contents of each type of display are stored in independent memory areas. uTo switch between the graphic display and text display Press !6(G↔T). You should also note that the key operations used to clear each type of display are different.
Before Starting Calculations... 1-1 uTo insert a step Example To change 2.362 to sin2.362 c.dgx ddddd ![ s • When you press ![ the insert location is indicated by the symbol ‘‘t’’. The next function or value you input is inserted at the location of ‘‘t’’. To abort the insert operation without inputting anything, move the cursor, press ![ again, or press d, e or w.
1-2 Memory k Variables This calculator comes with 28 variables as standard. You can use variables to store values to be used inside of calculations. Variables are identified by singleletter names, which are made up of the 26 letters of the alphabet, plus r and θ. The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. Variable contents are retained even when you turn power off.
Memory k Function Memory 1-2 [OPTN]-[FMEM] Function memory is convenient for temporary storage of often-used expressions. For longer term storage, we recommend that you use the GRAPH Mode for expressions and the PRGM Mode for programs. P.27 • {STO}/{RCL}/{fn}/{SEE} ...
1-2 Memory uTo delete a function Example To delete the contents of function memory number 1 K6(g)6(g)3(FMEM)A 1(STO) 1(f1) • Executing the store operation while the display is blank deletes the function in the function memory you specify. uTo use stored functions Once you store a function in memory, you can recall it and use it for a calculation. This feature is very useful for quick and easy input of functions when programming or graphing.
Memory 1-2 2. Press w again to display the memory status screen. Number of bytes still free 3. Use f and c to move the highlighting and view the amount of memory (in bytes) used for storage of each type of data. The following table shows all of the data types that appear on the memory status screen.
1-2 Memory k Clearing Memory Contents Use the following procedure to clear data stored in memory. 1. In the memory status screen, use f and c to move the highlighting to the data type you want to clear. If the data type you select in step 1 allows deletion of specific data 2. Press 1 (DEL). 1 2 3 4 5 6 * This menu appears when you select List File. 3. Press the function key that corresponds to the data you want to delete.
