--
-- Grant of Unlimited Rights
--
-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others

--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that the static expression given for a number declaration may be
-- of any numeric type. Check that the type of a named number is
-- universal_integer or universal_real regardless of the type of the
-- static expression that provides its value.
--
-- TEST DESCRIPTION:
-- This test defines a large cross section of mixed type named numbers.
-- Well, obviously the named numbers don't have types (other than
-- universal_integer and universal_real) associated with them.
-- This test uses typed static values in the definition of several named
-- numbers, and then mixes the named numbers to ensure that their typed
-- origins do not interfere with the use of their values.
--
--
-- CHANGE HISTORY:
-- 10 OCT 95 SAIC Initial version
-- 11 APR 96 SAIC Fixed a few arithmetic errors for 2.1
-- 24 NOV 98 RLB Removed decimal types to insure that this
-- test is applicable to all implementations.
