-- OBJECTIVE:

|
|
-- Check that function Length, with Display_Format parameter, will
|
| 28 |
|
|
-- return the minimal length of a Numeric value that will be required
|
| 29 |
|
|
-- to hold the largest value of type Num represented as Format.
|
| 30 |
|
|
--
|
| 31 |
|
|
-- Check that function To_Decimal will produce a decimal type Num
|
| 32 |
|
|
-- result that corresponds to parameter Item as represented by
|
| 33 |
|
|
-- parameter Format.
|
| 34 |
|
|
--
|
| 35 |
|
|
-- Check that function To_Decimal propagates Conversion_Error when
|
| 36 |
|
|
-- the value represented by parameter Item is outside the range of
|
| 37 |
|
|
-- the Decimal_Type Num used to instantiate the package
|
| 38 |
|
|
-- Decimal_Conversions
|
| 39 |
|
|
--
|
| 40 |
|
|
-- Check that function To_Display returns a Numeric type result that
|
| 41 |
|
|
-- represents Item under the specific Display_Format.
|
| 42 |
|
|
--
|
| 43 |
|
|
-- Check that function To_Display propagates Conversion_Error when
|
| 44 |
|
|
-- parameter Item is negative and the specified Display_Format

| 45 |
|
|
-- parameter is Unsigned.

|
-- TEST DESCRIPTION:
|
| 48 |
|
|
-- This test checks the results from instantiated versions of three
|
| 49 |
|
|
-- functions within generic package Interfaces.COBOL.Decimal_Conversions.
|
| 50 |
|
|
-- This generic package is instantiated twice, with decimal types having
|
| 51 |
|
|
-- four and ten digits representation.
|
| 52 |
|
|
-- The function Length is validated with the Unsigned, Leading_Separate,
|
| 53 |
|
|
-- and Trailing_Separate Display_Format specifiers.
|
| 54 |
|
|
-- The results of function To_Decimal are verified in cases where it
|
| 55 |
|
|
-- is given a variety of Numeric and Display_Format type parameters.
|
| 56 |
|
|
-- Function To_Decimal is also checked to propagate Conversion_Error
|
| 57 |
|
|
-- when the value represented by parameter Item is outside the range
|
| 58 |
|
|
-- of the type used to instantiate the package.
|
| 59 |
|
|
-- The results of function To_Display are verified in cases where it
|
| 60 |
|
|
-- is given a variety of Num and Display_Format parameters. It is also
|
| 61 |
|
|
-- checked to ensure that it propagates Conversion_Error if parameter
|
| 62 |
|
|
-- Num is negative and the Format parameter is Unsigned.
|
| 63 |
|
|
--
|
| 64 |
|
|
-- This test assumes that the following characters are all included
|
| 65 |
|
|
-- in the implementation defined type Interfaces.COBOL.COBOL_Character:
|
| 66 |
|
|
-- ' ', '0'..'9', '+', '-', and '.'.
|
| 67 |
|
|
--
|
| 68 |
|
|
-- APPLICABILITY CRITERIA:
|
| 69 |
|
|
-- This test is applicable to all implementations that provide
|
| 70 |
|
|
-- package Interfaces.COBOL. If an implementation provides
|
| 71 |
|
|
-- package Interfaces.COBOL, this test must compile, execute, and
|
| 72 |
|
|
-- report "PASSED".
