--     Unlimited rights are defined in DFAR 252.227-7013(a)(19).  By making

--     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.
