| -- |
| -- OBJECTIVE: |
| -- Check that function Length in the generic package Decimal_Output |
| -- returns the number of characters in the edited output string |
| -- produced by function Image, for a particular decimal type, |
| -- currency string, and radix mark. |
| -- Check that function Valid in the generic package Decimal_Output |
| -- returns correct results based on the particular decimal value, |
| -- and the Picture and Currency string parameters. |
| -- |
| -- TEST DESCRIPTION: |
| -- This test uses two instantiations of package Decimal_Output, one |
| -- for decimal data with delta 0.01, the other for decimal data with |
| -- delta 1.0. The functions Length and Valid found in this generic |
| -- package are evaluated for each instantiation. |
| -- Function Length is examined with picture and currency string input |
| -- parameters of different sizes. |
| -- Function Valid is examined with a decimal type data item, picture |
| -- object, and currency string, for cases that are both valid and |
| -- invalid (Layout_Error would result from the particular items as |
| -- input parameters to function Image). |
| -- |
