+-- These rights include rights to use, duplicate, release or disclose the

+-- 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 one operand is of an ordinary fixed point type.
+--
+-- Check that if the mathematical result is between multiples of the
+-- small of the result type, the result is truncated toward zero.
+-- Check that if the attribute 'Round is applied to the mathematical
+-- result, however, the result is rounded to the nearest multiple of
+-- the small (away from zero if the result is midway between two
+-- multiples of the small).
+--
+-- TEST DESCRIPTION:
+-- Two decimal fixed point types A and B are declared, one with a
+-- Machine_Radix value of 2, and one with a value of 10. An ordinary
+-- fixed point type C is declared with a delta value different from
+-- those of A and B (although still a power of 10). For type A (and B),
+-- checks are performed on the following operations, where one operand
+-- type is C, and the other operand type and the result type is A (or B):
+--
+-- - Multiplication.
+-- - Multiplication, where the attribute 'Round is applied to the
+-- result.
+-- - Division.
+-- - Division, where the attribute 'Round is applied to the result.
+--
+-- Each operation is performed within a loop, where one operand is
+-- always the same variable. After the loop completes, the cumulative
+-- total contained in this variable is compared with the expected
+-- result.
+--
+-- APPLICABILITY CRITERIA:
+-- This test is only applicable for a compiler attempting validation
+-- for the Information Systems Annex.
+--
+--
+-- CHANGE HISTORY:
+-- 22 Mar 96 SAIC Prerelease version for ACVC 2.1.
+-- 11 Aug 96 SAIC ACVC 2.1: In RADIX_2_MULTIPLICATION, corrected
+-- value of Rate. Corrected associated commentary.
