cacoshl(3M)

Name

cacosh, cacoshf, cacoshl - complex arc hyperbolic cosine functions

Synopsis

c99 [ flag... ] file... –lm [ library... ]
#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 [ -iπ, +iπ ] along the imaginary axis.

Errors

No errors are defined.
