CARG(3) Linux Programmer's Manual CARG(3)[top]NAMEcarg, cargf, cargl - calculate the complex argumentSYNOPSIS#include <complex.h> double carg(double complex z); float cargf(float complex z); long double cargl(long double complex z); Link with-lm.DESCRIPTIONA complex number can be described by two real coordinates. One may use rectangular coordinates and gets z = x + I * y where 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 the range of [,pi].-piVERSIONSThese functions first appeared in glibc in version 2.1.CONFORMING TOC99.SEE ALSOcabs(3), complex(7)COLOPHONThis page is part of release 3.53 of the Linux man-pages project.
