NAME
       cacosh, cacoshf - complex arc hyperbolic cosine functions

SYNOPSIS
       #include <complex.h>

       double complex cacosh(double complex z);
       float complex cacoshf(float 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 VALUE
       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.
