25--
26-- OBJECTIVE:
27--      Check that the static expression given for a number declaration may be
28--      of any numeric type.  Check that the type of a named number is
29--      universal_integer or universal_real regardless of the type of the
30--      static expression that provides its value.
31--
32-- TEST DESCRIPTION:
33--      This test defines a large cross section of mixed type named numbers.
34--      Well, obviously the named numbers don't have types (other than
35--      universal_integer and universal_real) associated with them.
36--      This test uses typed static values in the definition of several named
37--      numbers, and then mixes the named numbers to ensure that their typed
38--      origins do not interfere with the use of their values.
39--
40--
41-- CHANGE HISTORY:
42--      10 OCT 95   SAIC   Initial version
43--      11 APR 96   SAIC   Fixed a few arithmetic errors for 2.1
44--      24 NOV 98   RLB    Removed decimal types to insure that this
45--                         test is applicable to all implementations.
