CACOS(3M) Mathematical Library Functions CACOS(3M)

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.
