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 = 48.
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.
40
41 -- APPLICABILITY CRITERIA:
42 -- THIS TEST IS APPLICABLE FOR IMPLEMENTATIONS WHICH HAVE A
43 -- 'MAX_MANTISSA OF 47 OR GREATER.
44
45 -- IF 'MAX_MANTISSA >= 47 IS NOT SUPPORTED THEN THE DECLARATION OF
46 -- 'TYPE FX_OP5' MUST BE REJECTED.
