25 -- OBJECTIVE:
26 -- CHECK THAT THE OPERATOR "*" PRODUCES CORRECT RESULTS
27 -- FOR MIXED FIXED POINT AND INTEGER TYPES USING 4 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) INTEGER * FIXED WHEN ALL VALUES ARE MODEL NUMBERS.
34 -- B) FIXED * INTEGER WHEN ALL VALUES ARE MODEL NUMBERS.
35 -- C) INTEGER * FIXED FOR NON-MODEL NUMBERS.
36 -- D) FIXED * INTEGER FOR NON-MODEL NUMBERS.
37 --
38 -- REPEAT FOR MINIMUM REQUIRED WORD LENGTHS OF 12, 16, 32 AND 48,
39 -- WITH RANGE <, =, AND > THAN 1.0 AND
40 -- WITH DELTA <, =, AND > THAN 1.0.
41
42 -- HISTORY:
43 -- NTW 09/08/86 CREATED ORIGINAL TEST.
44 -- RJW 11/05/86 REVISED COMMENTS.
45 -- DHH 01/13/88 ADDED APPLICABILITY CRITERIA AND STANDARD HEADER.
46 -- BCB 04/27/90 REVISED APPLICABILITY CRITERIA.
47 -- BCB 10/03/90 REMOVED APPLICABILITY CRITERIA AND N/A => ERROR
48 -- LINE. CHANGED EXTENSION FROM '.DEP' TO '.ADA'.
