FUNCTION
<<cimag>>, <<cimagf>>, <<cimagl>>---imaginary part
INDEX
cimag
INDEX
cimagf
INDEX
cimagl
ANSI_SYNOPSIS
#include <complex.h>
double cimag(double complex <[z]>);
float cimagf(float complex <[z]>);
long double cimagl(long double complex <[z]>);
DESCRIPTION
These functions compute the imaginary part of <[z]>.
<<cimagf>> is identical to <<cimag>>, except that it performs
its calculations on <<float complex>>.
<<cimagl>> is identical to <<cimag>>, except that it performs
its calculations on <<long double complex>>.
RETURNS
The cimag* functions return the imaginary part value (as a real).
PORTABILITY
<<cimag>>, <<cimagf>> and <<cimagl>> are ISO C99
QUICKREF
<<cimag>>, <<cimagf>> and <<cimagl>> are ISO C99
