Mathematical Library Functions                           carg(3M)



NAME
     carg, cargf, cargl - complex argument functions

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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 ].

ERORS
     No errors are defined.
