| --* |
| -- |
| -- OBJECTIVE: |
| -- Check that the subprograms defined in the package |
| -- Ada.Numerics.Generic_Complex_Types provide the prescribed results. |
| -- Specifically, check the various versions of functions "+" and "-". |
| -- |
| -- TEST DESCRIPTION: |
| -- This test checks that the subprograms "+" and "-" defined in the |
| -- Generic_Complex_Types package provide the results prescribed for the |
| -- evaluation of these complex arithmetic operations. The functions |
| -- Re and Im are used to extract the appropriate component of the |
| -- complex result, in order that the prescribed result component can be |
| -- verified. |
| -- The generic package is instantiated with a real type (new Float), |
| -- and the results produced by the specified subprograms are verified. |
| -- |
| -- SPECIAL REQUIREMENTS: |
| -- This test can be run in either "relaxed" or "strict" mode. |
