NAME
casinh, casinhf, casinhl - complex arc hyperbolic sine functions
SYNOPSIS
#include <complex.h>
double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
DESCRIPTION
These functions shall compute the complex arc hyperbolic sine of z,
with branch cuts outside the interval [-i, +i] along the imaginary
axis.
RETURN VALUE
These functions shall return the complex arc hyperbolic sine value, in
the range of a strip mathematically unbounded along the real axis and
in the interval [-ipi/2, +ipi/2] along the imaginary axis.
