-- OBJECTIVE:
--     WHEN THE TYPE MARK IN A QUALIFIED EXPRESSION DENOTES A FLOATING
--     POINT TYPE, CHECK THAT CONSTRAINT_ERROR IS RAISED WHEN THE VALUE
--     OF THE OPERAND DOES NOT LIE WITHIN THE RANGE OF THE TYPE MARK.

-- HISTORY:
--     RJW 07/23/86  CREATED ORIGINAL TEST.
--     BCB 08/19/87  CHANGED HEADER TO STANDARD HEADER FORMAT.  ADDED
--                   TEST FOR UPPER SIDE OF RANGE.
