double cimag(double complex z);
float cimagf(float complex z);
long double cimagl(long double complex z);
[CX] 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 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.
For a variable z of complex type:z == creal(z) + cimag(z)*I
