NAME
       coshd64(), coshd128(), coshd32() - decimal hyperbolic cosine functions

SYNOPSIS
DESCRIPTION
       returns the hyperbolic cosine of x.

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

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

       These  math  functions  are supported for HP-UX 11i Version 3 September
       2008 Update and forward.

USAGE
       To use any of these functions, compile with the option.

       Make sure your program defines and then includes

       Link in the math library by specifying or on the linking command line.

       For more information, see the at the following site:

RETURN VALUE
       returns 1.

       If x returns +infinity.

       If x is NaN, returns NaN.

       returns +infinity (or, in some non-default  rounding  direction	modes,
       the  maximum  finite  number) in lieu of a value whose magnitude is too
       large, and raises the overflow and inexact exceptions.

       raises the inexact exception whenever a rounded result does  not	 equal
       the mathematical result.

ERRORS
       If the correct value would overflow, sets to

STANDARDS CONFORMANCE
       These functions conform to ISO/IEC TR 24732, "Extension	for  the  pro‐
       gramming language C to support decimal floating-point arithmetic".
