NAMEcarg, cargf, cargl − calculate the complex argument

LIBRARYMath library (libm, −lm)

SYNOPSIS#include <complex.h>double carg(double complex z); float cargf(float complex z); long double cargl(long double complex z);

DESCRIPTIONThese functions calculate the complex argument (also called phase angle) of z, with a branch cut along the negative real axis. A complex number can be described by two real coordinates. One may use rectangular coordinates and gets z = x + I * ywhere x = creal(z) and y = cimag(z). Or one may use polar coordinates and gets z = r * cexp(I * a)where r = cabs(z) is the "radius", the "modulus", the absolute value of z, and a = carg(z) is the "phase angle", the argument of z. One has: tan(carg(z)) = cimag(z) / creal(z)

RETURN VALUEThe return value is in the range of [−pi,pi].

VERSIONSThese functions were added in glibc 2.1.
