cimag, cimagf, cimagl - get imaginary part of a complex number
#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.
