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.

CONFORMING TO
