--
-- OBJECTIVE:
--      Check that the static expression given for a number declaration may be
--      of any numeric type.  Check that the type of a named number is
--      universal_integer or universal_real regardless of the type of the
--      static expression that provides its value.
--
-- TEST DESCRIPTION:
--      This test defines a large cross section of mixed type named numbers.
--      Well, obviously the named numbers don't have types (other than
--      universal_integer and universal_real) associated with them.
--      This test uses typed static values in the definition of several named
--      numbers, and then mixes the named numbers to ensure that their typed
--      origins do not interfere with the use of their values.
--
--
-- CHANGE HISTORY:
--      10 OCT 95   SAIC   Initial version
--      11 APR 96   SAIC   Fixed a few arithmetic errors for 2.1
--      24 NOV 98   RLB    Removed decimal types to insure that this
--                         test is applicable to all implementations.
