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

13       casinh, casinhf, casinhl — complex arc hyperbolic sine functions
14

SYNOPSIS

16       #include <complex.h>
17
18       double complex casinh(double complex z);
19       float complex casinhf(float complex z);
20       long double complex casinhl(long double complex z);
21

DESCRIPTION

23       The functionality described on this reference page is aligned with  the
24       ISO C  standard.  Any  conflict between the requirements described here
25       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
26       defers to the ISO C standard.
27
28       These  functions  shall  compute  the complex arc hyperbolic sine of z,
29       with branch cuts outside the  interval  [−i, +i]  along  the  imaginary
30       axis.
31

RETURN VALUE

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