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

     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.
