NAME
       cacos, cacosf, cacosl - complex arc cosine functions

SYNOPSIS
       #include <complex.h>

       double complex cacos(double complex z);
       float complex cacosf(float complex z);
       long double complex cacosl(long double complex z);

DESCRIPTION
       These functions shall compute the complex arc cosine of z, with branch cuts outside the interval [-1, +1] along the real axis.

RETURN VALUE
       These functions shall 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.

ERRORS
       No errors are defined.
