cimag(3M)

NAME

cimag(), cimagf(), cimagl(), cimagw(), cimagq() — the imaginary part of a complex value

SYNOPSIS

#include <complex.h>

double cimag(double complex z);

float cimagf(float complex z);

long double cimagl(long double complex z);

extended cimagw(extended complex z);

quad cimagq(quad complex z);

DESCRIPTION

These functions are available only for Itanium-based systems.

cimag() returns the imaginary part of z (as a real).

cimagf() is a float complex version of cimag(); it takes a float complex argument and returns a float result.

cimagl() is a long double complex version of cimag(); it takes a long double complex argument and returns a long double result.

cimagw() is an extended complex version of cimag(); it takes an extended complex argument and returns an extended result.

cimagq() is equivalent to cimagl() on HP-UX systems.

These functions raise no floating-point exceptions.

USAGE

To use these functions, compile with the default -Ae option. To use cimagw() or cimagq(), compile with the -fpwidetypes option. Make sure your program includes <complex.h>. Link in the math library by specifying -lm on the compiler or linker command line.

ERRORS

No errors are defined.

STANDARDS CONFORMANCE

cimag(), cimagf(), cimagl() : ISO/IEC C99 (including Annex G, ``IEC 60559-compatible complex arithmetic'')
