--
-- OBJECTIVE:
--      Check that the binary adding operators for a decimal fixed point type
--      return values that are integral multiples of the small of the type.
--    
-- TEST DESCRIPTION:
--      The test verifies that decimal addition and subtraction behave as
--      expected for types with various digits, delta, and Machine_Radix
--      values. Types with the minimum values for Decimal.Max_Digits and
--      Decimal.Max_Scale (18) are included.
--
--      Two kinds of checks are performed for each type. In the first check,
--      the iteration, operation, and operand counts in the foundation and
--      the operation tables in this test are given values such that, when the
--      operations loop is complete, each operand will have been added to and
--      subtracted from the loop's cumulator variable the same number of times,
--      albeit in varying order. Thus, the result returned by the operations
--      loop should have the same value as that used to initialize the
--      cumulator (in this test, zero).
--
--      In the second check, the same operation (addition for some types and
--      subtraction for others) is performed during each loop iteration,
--      resulting in a cumulative total which is checked against an expected
--      value.
--
-- TEST FILES:
--      The following files comprise this test:
--
--         FXF2A00.A
--      -> CXF2A01.A
--
-- APPLICABILITY CRITERIA:
--      This test is only applicable for a compiler attempting validation
--      for the Information Systems Annex.
