-- CD2A53A.ADA
-- 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
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED

--*
-- OBJECTIVE:
-- CHECK THAT WHEN SIZE AND SMALL SPECIFICATIONS ARE GIVEN FOR A
-- FIXED POINT TYPE, THEN OPERATIONS ON VALUES OF SUCH A TYPE ARE
-- NOT AFFECTED BY THE REPRESENTATION CLAUSE.
-- APPLICABILITY CRITERIA:
-- All implementations must attempt to compile this test.
--
-- For implementations validating against Systems Programming Annex (C)
-- and which support decimal small values:
-- The test must compile, bind, execute, report PASSED, and
-- complete normally.
--
-- For other implementations:
-- This test may produce at least one error message at compilation,
-- and the error message is associated with one of the items marked:
-- -- N/A => ERROR.
-- The test will be recorded as Not_Applicable.
-- Otherwise, the test must execute and report PASSED.
--
-- All other behaviors are FAILING.
--
-- HISTORY:
-- BCB 08/24/87 CREATED ORIGINAL TEST.
-- DHH 04/12/89 CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
-- OPERATORS ON 'SIZE TESTS, AND CHANGED 'SIZE CLAUSE
-- SO THAT IT IS NOT A POWER OF TWO.
-- WMC 04/01/92 ELIMINATED TEST REDUNDANCIES.
-- RLB 11/24/98 Added Ada 95 applicability criteria.
