NAME

conj, conjf, conjl - calculate the complex conjugate

SYNOPSIS

#include <complex.h>
double complex conj(double complex z);

long double complex conjl(long double complex z);
Link with -lm.

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 first appeared in glibc in version 2.1.
