conj, conjf, conjl − calculate the complex conjugate
#include <complex.h>
double complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex z);
The conj() function returns the complex conjugate value of z. That is the value obtained by changing the sign of the imaginary part.
One has cabs(z) = csqrt(z * conj(z)).
