-- CXF2A02.A
--
-- 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
-- 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 multiplying operators for a decimal fixed point type
-- return values that are integral multiples of the small of the type.
-- Check the case where the operand and result types are the same.
--
-- Check that if the mathematical result is between multiples of the
-- small of the result type, the result is truncated toward zero.
--
-- TEST DESCRIPTION:
-- The test verifies that decimal multiplication and division behave as
-- expected for types with various digits, delta, and Machine_Radix
-- values.
--
-- The iteration, operation, and operand counts in the foundation, and
-- the operations and operand tables in the test, are given values such
-- that, when the operations loop is complete, truncation of inexact
-- results should cause the result returned by the operations loop to be
-- the same as that used to initialize the loop's cumulator variable (in
-- this test, one).
--
-- TEST FILES:
-- This test consists of the following files:
--
-- FXF2A00.A
-- -> CXF2A02.A
--
-- APPLICABILITY CRITERIA:
-- This test is only applicable for a compiler attempting validation
-- for the Information Systems Annex.
--
--
-- CHANGE HISTORY:
-- 13 Mar 96 SAIC Prerelease version for ACVC 2.1.
-- 04 Aug 96 SAIC Updated prologue.
--
