cimag, cimagf, cimagl − get imaginary part of a complex number

#include <complex.h>

double cimag(double complex z);

float cimagf(float double complex z);

long double cimagl(long double complex z);

The cimag() function returns the imaginary part of the complex number z.

One has z = creal(z) + I*cimag(z).

The gcc supports also __imag__. That is a GNU extension.
