-- in DFAR 252.227-7013(a)(19). By making this public release, the ACAA
-- intends to confer upon all recipients unlimited rights equal to those
-- held by the ACAA. These rights include rights to use, duplicate,

-- Notice
--
-- The ACAA has created and maintains the Ada Conformity Assessment Test

-- OBJECTIVE:
-- For exponentiation of floating point types, check that
-- Constraint_Error is raised (or, if no exception is raised and
-- Machine_Overflows is False, that a result is produced) if the
-- result is outside of the range of the base type.
-- This tests digits 5.
-- HISTORY:
-- 04/30/03 RLB Created test from old C45622A and C45624A.
