NAME

6       casinh, casinhf, casinhl - complex arc hyperbolic sine functions
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex casinh(double complex z);
12       float complex casinhf(float complex z);
13       long double complex casinhl(long double complex z);

DESCRIPTION

17       These  functions  shall  compute  the complex arc hyperbolic sine of z,
18       with branch cuts outside the  interval  [-i, +i]  along  the  imaginary
19       axis.
20

RETURN VALUE

22       These  functions shall return the complex arc hyperbolic sine value, in
23       the range of a strip mathematically unbounded along the real  axis  and
24       in the interval [-ipi/2, +ipi/2] along the imaginary axis.
