CONJ(3) Linux Programmer s Manual CONJ(3)

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.
