PROGRAM FILE 40: ACCURACY OF SUBTRACTION
ANSI STANDARD 7.2, 7.4, 7.6

*** NOTE: THIS PROGRAM MAKES USE OF 'READ' AND 'DATA'
WHICH HAVE NOT YET BEEN TESTED. IF SUBSEQUENT TESTS SHOW
THESE FEATURES TO BE INCORRECTLY IMPLEMENTED, THEN THE
VALIDITY OF THE RESULTS OF THIS TEST ROUTINE IS DOUBTFUL.

SECTION 40.1 ACCURACY OF SUBTRACTION.

THIS SECTION TESTS THE ACCURACY OF SUBTRACTION. THE COMPUTED
RESULT IS COMPARED WITH A RANGE ESTABLISHED BY PERTURBING
EACH OPERAND BY 1 IN ITS 6TH DIGIT. THE RESULT PASSES IF
IT FALLS WITHIN THE EXTREME VALUES GENERATED BY THIS
PERTURBATION (ACCURATE TO SIX DIGITS).

THIS TEST IS INFORMATIVE ONLY, SINCE THE ANSI STANDARD
DOES NOT MANDATE ANY ACCURACY FOR NUMERIC EXPRESSIONS.
