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.
