NAME

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

Math library (libm, -lm)

bash

#include <complex.h>

bash

double cimag(double complex \nz\n);\n
\nfloat cimagf(float complex \nz\n);\n
\nlong double cimagl(long double complex \nz\n);

These functions return the imaginary part of the complex number z.

One has:

bash

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