| -- |
| -- OBJECTIVE: |
| -- 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. |
| -- |
| -- Check that the function Length with Packed_Format parameter returns |
| -- the minimal length of a Packed_Decimal value sufficient to hold any |
| -- value of type Num when represented according to parameter Format. |
| -- |
| -- Check that the function To_Decimal with Packed_Decimal and |
| -- Packed_Format parameters produces a decimal type value corresponding |
| -- to the Packed_Decimal parameter value Item, under the conditions of |
| -- the Packed_Format parameter Format. |
| -- |
| -- Check that the function To_Packed with Decimal (Num) and |
| -- Packed_Format parameters produces a Packed_Decimal result that |
| -- corresponds to the decimal parameter under conditions of the |
| -- Packed_Format parameter. |
| -- |
| -- Check that Conversion_Error is propagated by function To_Packed if |
| -- the value of the decimal parameter Item is negative and the specified |
| -- Packed_Format parameter is Packed_Unsigned. |
| -- |
| -- |
| -- TEST DESCRIPTION: |
| -- This test checks the results from instantiated versions of |
| -- several functions that deal with parameters or results of type |
| -- Packed_Decimal. 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". |
