+-- OBJECTIVE:
+--      Check that multiplication and division of decimal fixed point 
+--      numbers produce exact results.
+--
+-- TEST DESCRIPTION:
+--      Check that multiplication and division of decimal fixed point 
+--      numbers produce exact results.
+--
+-- SPECIAL REQUIREMENTS
+--      The Strict Mode for the numerical accuracy must be
+--      selected.  The method by which this mode is selected
+--      is implementation dependent.
+--
+-- APPLICABILITY CRITERIA:
+--      This test applies only to implementations supporting the
+--      Numerics Annex.
+--      This test only applies to the Strict Mode for numerical
+--      accuracy.
+--      This test applies only to implementations supporting
+--      decimal fixed point types of at least 9 digits.
