NAME
       casin(), casinf(), casinl(), casinw(), casinq() - complex arcsine functions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns	the  complex  arcsine  of  z,  in  the	range  of  a  strip  mathematically unbounded along the imaginary axis and in the interval
       [-Pi/2,+Pi/2] along the real axis.  Branch cuts are outside the interval [-1,+1] along the real axis.

       is a version of it takes a argument and returns a result.

       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To use these functions, compile with the default option.  To use compile with the option.  Make sure your program includes Link in the math
       library by specifying on the compiler or linker command line.

RETURN VALUE
       = and is an odd function.

       returns 0+i0.

       returns Pi/2+iInf for positive-signed finite y.

       returns NaN+iNaN and may raise the invalid exception for finite y.

       returns +0+iInf for positive-signed finite x.

       returns Pi/4+iInf.

       returns NaN+iInf.

       returns +0+iNaN.

       returns NaN+iNaN and may raise the invalid exception for finite nonzero x.

       (where the sign of the imaginary part of the result is unspecified).

       returns NaN+iNaN.

ERRORS
