NAME
       carg, cargf, cargl - complex argument functions

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <complex.h>

       double carg(double complex z);

       float cargf(float complex z);

       long double cargl(long double complex z);

DESCRIPTION
       These functions compute the argument (also called phase angle) of z, with a branch cut along the negative real axis.

RETURN VALUES
       These functions return the value of the argument in the interval [ -pi, +pi ].
