26 -- CHECK THAT THE OPERATOR "/" PRODUCES CORRECT RESULTS
27 -- FOR FIXED POINT TYPES USING 3 SUBTESTS.
28 -- THIS TEST REQUIRES MIN_WORD_LENGTH = 16.
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.
