--

-- 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.
