carg, cargf, cargl - complex argument functions
double carg(double complex z);
float cargf(float complex z);
long double cargl(long double complex z);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.
These functions shall compute the argument (also called phase angle) of z, with a branch cut along the negative real axis.
These functions shall return the value of the argument in the interval [-, +].
No errors are defined.
