NAME
       casin(), casinf(), casinl(), casinw(), casinq() - complex arcsine func‐
       tions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns the complex arcsine of z, in the range of  a  strip  mathemati‐
       cally   unbounded   along  the  imaginary  axis	and  in	 the  interval
       [-Pi/2,+Pi/2] along the real axis.  Branch cuts are outside the	inter‐
       val [-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 com‐
       pile 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
       No errors are defined.
