-- OBJECTIVE:
26
--     CHECK THAT THE OPERATOR "/" PRODUCES CORRECT RESULTS
27
--     FOR FIXED POINT TYPES USING 3 SUBTESTS.
28
--       THIS TEST REQUIRES MIN_WORD_LENGTH = 12.
29
--       THIS TEST USES VALUES OF DELTA WHICH ARE GREATER THAN OR
30
--       EQUAL TO 0.5.
31
--
32
--     TEST CASES ARE:
33
--       A) THE OPERATOR /, A, B, AND A / B ALL MODEL NUMBERS.
34
--       B) THE OPERATOR /, A, B MODEL NUMBERS A / B NOT.
35
--       C) THE OPERATOR /, USING NO MODEL NUMBERS.
36
--
37
--     REPEAT FOR MINIMUM REQUIRED WORD LENGTHS OF 12, 16, 32 AND 48,
38
--     WITH RANGE <, =, AND > THAN 1.0 AND
39
--     WITH DELTA <, =, AND > THAN 1.0.

41
-- HISTORY:
42
--     NTW 09/08/86 CREATED ORIGINAL TEST.
43
--     RJW 11/05/86 REVISED COMMENTS.
44
--     DHH 01/13/88 ADDED APPLICABILITY CRITERIA AND STANDARD HEADER.
45
--     RDH 04/27/90 REVISED APPLICABILITY CRITERIA.
46
--     BCB 10/03/90 REMOVED APPLICABILITY CRITERIA AND N/A => ERROR
