CIMAG(3) complex math routines CIMAG(3) NAME cimag, cimagf, cimagl - get imaginary part of a complex number SYNOPSIS #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.
