cacos, cacosf, cacosl - complex arc cosine functions
c99 [ flag... ] file... -lm [ library... ] #include <complex.h> double complex cacos(double complex z);
float complex cacosf(float complex z);
long double complex cacosl(long double complex z);
These functions compute the complex arc cosine of z, with branch cuts outside the interval [ -1, +1 ] along the real axis.
These functions return the complex arc cosine value, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [ 0, pi ] along the real axis.
