-- CXB4008.A
--
-- Grant of Unlimited Rights
--
-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that the function To_Decimal with Binary parameter will return
-- the corresponding value of the decimal type Num.
--
-- Check that the function To_Decimal with Long_Binary parameter will
-- return the corresponding value of the decimal type Num.
--
-- Check that both of the To_Decimal functions described above will
-- propagate Conversion_Error if the converted value Item is outside
-- the range of type Num.
--
-- Check that the function To_Binary converts a value of the Ada
-- decimal type Num into a Binary type value.
--
-- Check that the function To_Long_Binary converts a value of the Ada
-- decimal type Num into a Long_Binary type value.
--
-- TEST DESCRIPTION:
-- This test uses several instantiations of generic package
-- Decimal_Conversions to provide appropriate test material.
-- Two of the instantiations use decimal types as generic actuals
-- that include the implementation defined constants Max_Digits_Binary
-- and Max_Digits_Long_Binary in their definition.
--
-- Subtests are included for both versions of function To_Decimal,
-- (Binary and Long_Binary parameters), and include checks that
-- Conversion_Error is propagated under the appropriate circumstances.
-- Functions To_Binary and To_Long_Binary are "sanity" checked, to
-- ensure that the functions are available, and that the results are
-- appropriate based on their parameter input.
--
-- APPLICABILITY CRITERIA:
-- This test is applicable to all implementations that provide
-- package Interfaces.COBOL. If an implementation provides
-- package Interfaces.COBOL, this test must compile, execute, and
-- report "PASSED".
--
--
-- CHANGE HISTORY:
-- 21 Feb 96 SAIC Initial release for 2.1.
-- 10 Jun 96 SAIC Incorporated reviewer comments for ACVC 2.1.
-- 27 Oct 96 SAIC Incorporated reviewer comments.
