NAME

       conj, conjf, conjl - calculate the complex conjugate

LIBRARY

       Math library (libm, -lm)

SYNOPSIS

       #include <complex.h>

       double complex conj(double complex z);
       float complex conjf(float complex z);
       long double complex conjl(long double complex z);

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))
