NAME

cacosh, cacoshf, cacoshlcomplex arc hyperbolic cosine functions

SYNOPSIS

#include <complex.h>

double complex
cacosh(double complex z);

float complex
cacoshf(float complex z);

long double complex
cacoshl(long double complex z);

DESCRIPTION

These functions compute the complex arc hyperbolic cosine of z, with a branch cut at values less than 1 along the real axis.

RETURN VALUES

These functions return the complex arc hyperbolic cosine value, in the range of a half-strip of non-negative values along the real axis and in the interval [-i pi, +i pi] along the imaginary axis.

ERRORS

No errors are defined.
