--
-- OBJECTIVE:
-- Check that the specified exceptions are raised by the subprograms
-- defined in package Ada.Numerics.Generic_Complex_Elementary_Functions
-- given the prescribed input parameter values.
--
-- TEST DESCRIPTION:
-- This test checks that specific subprograms defined in the
-- package Ada.Numerics.Generic_Complex_Elementary_Functions raise the
-- exceptions Argument_Error and Constraint_Error when their input
-- parameter value are those specified as causing each exception.
-- In the case of Constraint_Error, the exception will be raised in
-- each test case, provided that the value of the attribute
-- 'Machine_Overflows (for the actual type of package
-- Generic_Complex_Type) is True.
--
-- APPLICABILITY CRITERIA:
-- This test only applies to implementations supporting the
-- numerics annex.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 16 Nov 95 SAIC Corrected visibility problems for ACVC 2.0.1.
-- 29 Sep 96 SAIC Incorporated reviewer comments.
-- 02 Jun 98 EDS Replace "_i" with "_One".
