Synopsis

#include <complex.h>

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

Description

The functions compute a complex arc cosine value.

Arguments
z - a complex number.

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

Return value

These functions return the complex arc cosine of z, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [0,&#x03C0] along the real axis.

Errors

No errors are defined.
