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

USAGE
       #include <complex.h>

       double cimag(double complex z);
       float cimagf(float complex z);
       long double cimagl(long double complex z);

       Link with -lm.

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

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

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