-- OBJECTIVE:
--     CHECK FIXED POINT MULTIPLICATION AND DIVISION WHEN 'SMALL OF
--     THE OPERANDS ARE NOT BOTH POWERS OF THE SAME BASE VALUE.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE TO IMPLEMENTATIONS WHICH SUPPORT
--     REPRESENTATION CLAUSES FOR 'SMALL WHICH ARE NOT POWERS OF TWO.

--     IF SUCH REPRESENTATION CLAUSES ARE NOT SUPPORTED, THEN THE
--     REPRESENTATION CLAUSE FOR CHECK_TYPE MUST BE REJECTED.

-- HISTORY:
--     BCB 02/02/88  CREATED ORIGINAL TEST.
