cimag cimagf cimagl — complex imaginary functions

#include <complex.h>

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

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.

These functions shall compute the imaginary part of z.

These functions shall return the imaginary part value (as a real).

No errors are defined.

None.

For a variable z of complex type:

z == creal(z) + cimag(z)*I

None.

None.
