NAME

complex - complex functions and macros

SYNOPSIS

#include <complex.h>

DESCRIPTION

This ﬁle contains declarations of all the functions in the Complex Library (described in Section (3M)).

It deﬁnes the types

extended The Integrity server 80-bit double-extended type.

quad An IEEE 754-compliant, 128-bit ﬂoating-point type. On HP-UX,

quad is a

synonym for

long double.

It deﬁnes the macros

complex Expands to _Complex, a keyword designating complex types.

imaginary Expands to _Imaginary, a keyword designating imaginary types.

These macros and the names of the real types, in combination, provide designations for the complex and

imaginary types

float complex

double complex

long double complex

extended complex

quad complex

float imaginary

double imaginary

long double imaginary

extended imaginary

quad imaginary

This ﬁle also deﬁnes the macros

_Imaginary_I Expands to a constant expression of type const float imaginary, with the

value of the imaginary unit (a number whose square is -1).

_Complex_I Expands to a constant expression of type const float complex, with the

value of the imaginary unit.

I Expands to _Imaginary_I. It can be used to efﬁciently construct complex

expressions in the style x + y*I, where x and y are real.

This header is for Integrity servers only. To use it, compile with the default

-Ae

option. To use the types

extended complex, quad complex, extended imaginary,orquad imaginary, compile

with the -fpwidetypes option.
