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.
