PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       casinh, casinhf, casinhl — complex arc hyperbolic sine functions
13

SYNOPSIS

15       #include <complex.h>
16
17       double complex casinh(double complex z);
18       float complex casinhf(float complex z);
19       long double complex casinhl(long double complex z);

DESCRIPTION

22       The functionality described on this reference page is aligned with  the
23       ISO C  standard.  Any  conflict between the requirements described here
24       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
25       defers to the ISO C standard.
26
27       These  functions  shall  compute  the complex arc hyperbolic sine of z,
28       with branch cuts outside the  interval  [-i, +i]  along  the  imaginary
29       axis.
30

RETURN VALUE

32       These  functions shall return the complex arc hyperbolic sine value, in
33       the range of a strip mathematically unbounded along the real  axis  and
34       in the interval [-iπ/2, +iπ/2] along the imaginary axis.
