26
-- OBJECTIVE:
27
--      Check that the sqrt function returns
28
--      results that are within the error bound allowed.
29

30
-- TEST DESCRIPTION:
31
--      This test contains three test packages that are almost
32
--      identical.  The first two packages differ only in the
33
--      floating point type that is being tested.  The first
34
--      and third package differ only in whether the generic
35
--      elementary functions package or the pre-instantiated
36
--      package is used.
37
--      The test package is not generic so that the arguments
38
--      and expected results for some of the test values
39
--      can be expressed as universal real instead of being
40
--      computed at runtime.
41
--
42
-- SPECIAL REQUIREMENTS
43
--      The Strict Mode for the numerical accuracy must be
44
--      selected.  The method by which this mode is selected
45
--      is implementation dependent.
46
--
47
-- APPLICABILITY CRITERIA:
48
--      This test applies only to implementations supporting the
49
--      Numerics Annex.
50
--      This test only applies to the Strict Mode for numerical
51
--      accuracy.
52
--
53
--
54
-- CHANGE HISTORY:
55
--       2 FEB 96   SAIC    Initial release for 2.1
56
--      18 AUG 96   SAIC    Made Check consistent with other tests.
