CIMAG(3) Linux Programmer's Manual CIMAG(3)
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.
These functions return 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.
For an explanation of the terms used in this section, see
attributes(7).
