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.
