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.

Since the rules for the formation of Packed_Decimal -- values are implementation defined, several of the subtests cannot -- directly check the accuracy of the results produced. Instead, they -- verify that the result is within a range of possible values, or -- that the result of one function can be converted back to the original -- actual parameter using a "mirror image" conversion function. -- -- 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: -- 12 Feb 96 SAIC Initial release for 2.1. -- 30 May 96 SAIC Incorporated reviewer comments for ACVC 2.1. -- 27 Oct 96 SAIC Incorporated reviewer comments. -- --! with Report; with Ada.Exceptions; with Interfaces.COBOL; -- N/A => ERROR procedure CXB4006 is begin Report.Test ("CXB4006", "Check that the functions Valid, Length, " & "To_Decimal, and To_Packed specific to " & "Packed_Decimal parameters produce correct " & "results"); Test_Block: declare use Interfaces.COBOL; use Ada.Exceptions; use type Interfaces.COBOL.Numeric; type Decimal_Type_1 is delta 0.1 digits 6; type Decimal_Type_2 is delta 0.01 digits 8; type Decimal_Type_3 is delta 0.001 digits 10; type Decimal_Type_4 is delta 0.0001 digits 12; package Pack_1 is new Decimal_Conversions(Decimal_Type_1); package Pack_2 is new Decimal_Conversions(Decimal_Type_2); package Pack_3 is new Decimal_Conversions(Decimal_Type_3); package Pack_4 is new Decimal_Conversions(Decimal_Type_4); TC_Dec_1 : Decimal_Type_1 := 12345.6; TC_Dec_2 : Decimal_Type_2 := 123456.78; TC_Dec_3 : Decimal_Type_3 := 1234567.890; TC_Dec_4 : Decimal_Type_4 := 12345678.9012; TC_Min_Length : Natural := 1; TC_Max_Length : Natural := 16; begin -- Check that the function Valid with Packed_Decimal and Packed_Format -- parameters returns True if Item (the Packed_Decimal parameter) has -- a value consistent with the Packed_Format parameter. -- Note: Since the formation rules for Packed_Decimal values are -- implementation defined, the parameter values here are -- created by function To_Packed.
