Synopsis

#include <complex.h>

double complex conj(double complex z);
float complex conjf(float complex z);

Description

These functions return 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))

Versions

These functions were added in glibc 2.1.
