| -- OBJECTIVE: |
| -- Check that the function Valid with Byte_Array and Binary_Format |
| -- parameters returns True if the Byte_Array parameter corresponds |
| -- to any value inside the range of type Num. |
| -- Check that function Valid returns False if the Byte_Array parameter |
| -- corresponds to a value outside the range of Num. |
| -- |
| -- Check that function Length with Binary_Format parameter will return |
| -- the minimum length of a Byte_Array value required to hold any value |
| -- of decimal type Num. |
| -- |
| -- Check that function To_Decimal with Byte_Array and Binary_Format |
| -- parameters will return a decimal type value that corresponds to |
| -- parameter Item (of type Byte_Array) under the specified Format. |
| -- |
| -- Check that Conversion_Error is propagated by function To_Decimal if |
| -- the Byte_Array parameter Item represents a decimal value outside the |
| -- range of decimal type Num. |
| -- |
| -- Check that function To_Binary will produce a Byte_Array result that |
| -- corresponds to the decimal type parameter Item, under the specified |
| -- Binary_Format. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test uses several instantiations of generic package |
| -- Decimal_Conversions to provide appropriate test material. |
| -- This test uses the function To_Binary to create all Byte_Array |
| -- parameter values used in calls to functions Valid and To_Decimal. |
| -- The function Valid is tested with parameters to provide both |
| -- valid and invalid expected results. This test also checks that |
| -- Function To_Decimal produces expected results in cases where each |
| -- of the three predefined Binary_Format constants are used in the |
| -- function calls. In addition, the prescribed propagation of |
| -- Conversion_Error by function To_Decimal is verified. |
| -- |
| -- 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". |
