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 [ -ipi, +ipi ] along the imaginary axis.

ERRORS
       No errors are defined.
