NAME

conj, conjf, conjl - calculate the complex conjugate

SYNOPSIS

#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.

DESCRIPTION

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))

VERSIONS

These functions first appeared in glibc in version 2.1.

ATTRIBUTES

Multithreading (see pthreads(7))

The conj(), conjf(), and conjl() functions are thread-safe.
