- PROGRAM FILE 25: MULTIPLY, DIVIDE, AND INVOLUTE
- ANSI STANDARD 7.2, 7.4
-
- THIS PROGRAM TESTS THE GROSS SEMANTIC CHARACTERISTICS OF
- THE MULTIPLY, DIVIDE, AND INVOLUTION OPERATORS FOR THE
- CONSTRUCTION OF NUMERIC EXPRESSIONS.
-
- EXPRESSIONS USING ONLY ONE OPERATOR AND CONSTANTS AND
- SIMPLE VARIABLES ARE EVALUATED, AND THE RESULTS TESTED
- AGAINST THE CORRECT VALUE. CONSTANTS ARE EXPRESSED IN
- NR1, NR2, AND NR3 FORM. THE VALUES OF THE OPERANDS AND
- RESULTS ARE RESTRICTED TO INTEGERS AND SIMPLE FRACTIONS
- TO AVOID ACCURACY PROBLEMS (ACCURACY IS ADDRESSED IN
- LATER TESTS).
