NAME
       cacos(), cacosf(), cacosl(), cacosw(), cacosq() - complex arccosine functions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns	the  complex  arccosine of z, in the range of a strip mathematically unbounded along the imaginary axis and in the interval [0,Pi]
       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 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 and link in  the
       math library by specifying on the compiler or linker command line.

RETURN VALUE
       =

       returns Pi/2-i0.

       returns Pi/2+iNaN.

       returns Pi/2-iInf, for finite x.

       returns NaN+iNaN and optionally raises the invalid floating-point exception, for nonzero finite x.

       returns Pi-iInf, for positive-signed finite y.

       returns +0-iInf, for positive-signed finite y.

       returns 3Pi/4-iInf.

       returns Pi/4-iInf.

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

       returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite y.

       returns NaN-iInf.

       returns NaN+iNaN.
