NAME
cacosh, cacoshf, cacoshl - complex 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 shall 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 shall 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.

EXAMPLES
None.
APPLICATION USAGE
