-- OBJECTIVE:
|
27 |
|
|
-- Check that the subprograms defined in the package
|
28 |
|
|
-- Ada.Numerics.Generic_Complex_Types provide the prescribed results.
|

-- Specifically, check the various versions of functions "+" and "-".

|
-- TEST DESCRIPTION:
|
32 |
|
|
-- This test checks that the subprograms "+" and "-" defined in the
|
33 |
|
|
-- Generic_Complex_Types package provide the results prescribed for the
|
34 |
|
|
-- evaluation of these complex arithmetic operations. The functions
|
35 |
|
|
-- Re and Im are used to extract the appropriate component of the
|
36 |
|
|
-- complex result, in order that the prescribed result component can be
|
37 |
|
|
-- verified.
|
38 |
|
|
-- The generic package is instantiated with a real type (new Float),
|
39 |
|
|
-- and the results produced by the specified subprograms are verified.
|
40 |
|
|
--
|
41 |
|
|
-- SPECIAL REQUIREMENTS:
|
42 |
|
|
-- This test can be run in either "relaxed" or "strict" mode.
