- PROGRAM FILE 121: ACCURACY OF EXP FUNCTION.
- ANSI STANDARD 7.6, 8.4
-
- SECTION 121.1: ACCURACY OF EXP FUNCTION.
-
- THIS PROGRAM TESTS VALUES RETURNED BY INVOCATIONS OF THE
- EXP FUNCTION FOR ACCURACY. THE INVOCATION MUST RETURN,
- ACCURATE TO SIX DIGITS, SOME VALUE ACTUALLY TAKEN ON BY
- THE FUNCTION WITHIN A DOMAIN BOUNDED BY THE ACTUAL ARGUMENT
- PLUS OR MINUS ONE IN THE SIXTH DIGIT. ALSO, AN
- 'ERROR MEASURE' IS COMPUTED AND REPORTED. THIS MEASURE
- IS JUST 2 * THE ABSOLUTE ERROR OVER THE SIZE OF THE RANGE;
- THUS, A VALUE JUST BARELY PASSING OR FAILING WILL USUALLY
- HAVE A MEASURE OF ABOUT 1. A VALUE 3 TIMES
- AS INACCURATE AS EXPECTED WILL HAVE A MEASURE OF 3.
-
- THIS TEST IS INFORMATIVE ONLY, SINCE THE ANSI STANDARD
- DOES NOT MANDATE ANY ACCURACY FOR SUPPLIED-FUNCTIONS.
