25 -- 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 LESS THAN 0.5.
30 --
31 -- TEST CASES ARE:
32 -- A) THE OPERATOR *, A, B, AND A * B ALL MODEL NUMBERS.
33 -- B) THE OPERATOR *, A, B MODEL NUMBERS A * B NOT.
34 -- C) THE OPERATOR *, USING NO 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 -- RDH 04/27/90 REVISED APPLICABILITY CRITERIA.
