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