CONJ

NAME

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);

Link with −lm.

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)).
