[jira] [Created] (MATH-580) FastMath Performance Test should use larger ranges where the functions support them

ASF GitHub Bot (Jira)
FastMath Performance Test should use larger ranges where the functions support them
-----------------------------------------------------------------------------------

                 Key: MATH-580
                 URL: https://issues.apache.org/jira/browse/MATH-580
             Project: Commons Math
          Issue Type: Bug
            Reporter: Sebb


FastMath calculations should be faster than Math, especially over larger ranges of operands.

The Performance test code currently uses a very small range of operands (probably so the same range can be used for all tests).

The test should be enhanced to use much larger ranges where this is supported by the function under test.

----------------------------------

Not sure if this has been fixed in trunk, but the performance test code had some issues: http://blog.juma.me.uk/2011/02/23/performance-of-fastmath-from-commons-math/

Gilles commented on MATH-580:
-----------------------------

In revision 1184958, the test class "FastMathTestPerformance" contains an additional method that performs the same micro-benchmark using another utility.  You are very welcome to check the methodology (see also MATH-637).
