NAME
       cacos, cacosf, cacosl - complex arc cosine functions

SYNOPSIS
       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);

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

RETURN VALUES
       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.

ERRORS
       No errors are defined.
