CARG(3M) Mathematical Library Functions CARG(3M)

carg, cargf, cargl - complex argument functions

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);

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

These functions return the value of the argument in the interval [ −pi, +pi ].

No errors are defined.
