CASIN(3P)                  POSIX Programmer's Manual                 CASIN(3P)
PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       casin, casinf, casinl -- complex arc sine functions
SYNOPSIS
       #include <complex.h>
       double complex casin(double complex z);
       float complex casinf(float complex z);
       long double complex casinl(long double complex z);
DESCRIPTION
       The functionality described on this reference page is aligned with  the
       ISO C  standard.  Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1-2008
       defers to the ISO C standard.
       These  functions  shall  compute the complex arc sine of z, with branch
       cuts outside the interval [-1, +1] along the real axis.
RETURN VALUE
       These functions shall return the complex arc sine value, in  the  range
       of a strip mathematically unbounded along the imaginary axis and in the
       interval [-n/2, +n/2] along the real axis.
ERRORS
       No errors are defined.
