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

       C99.
