26 -- CHECK THAT THE OPERATOR "/" PRODUCES CORRECT RESULTS
27 -- FOR FIXED POINT TYPES USING 3 SUBTESTS.
28 -- THIS TEST REQUIRES MIN_WORD_LENGTH = 32.
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.
