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.
