--- 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

---
--- 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.
