25 -- OBJECTIVE:
26 -- CHECK THAT THE OPERATOR "/" PRODUCES CORRECT RESULTS
27 -- FOR MIXED FIXED POINT AND INTEGER TYPES USING 3 SUBTESTS.
28 -- THIS TEST REQUIRES MIN_WORD_LENGTH = 16.
29 -- THIS TEST USES VALUES OF DELTA WHICH ARE LESS THAN 0.5.
30 --
31 -- TEST CASES ARE:
32 -- A) FIXED / INTEGER WHEN ALL VALUES ARE MODEL NUMBERS.
33 -- B) FIXED / INTEGER WITH NUMERATOR MODEL NUMBER AND RESULT NOT.
34 -- C) FIXED / INTEGER FOR NON-MODEL NUMBERS.
35 --
36 -- REPEAT FOR MINIMUM REQUIRED WORD LENGTHS OF 12, 16, 32 AND 48,
37 -- WITH RANGE <, =, AND > THAN 1.0 AND
38 -- WITH DELTA <, =, AND > THAN 1.0.

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