#include <complex.h>
double
cimag(double complex z);
float cimagf(float complex z);
long double cimagl(long double complex
z);
Link with −lm.
The cimag() function returns the imaginary part of the complex number z.
One has:
z = creal(z) + I * cimag(z)
These functions first appeared in glibc in version 2.1.

gcc also supports __imag__. That is a GNU extension.
