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.
