Ismael Juma commented on MATH-580:
----------------------------------
Not sure if this has been fixed in trunk, but the performance test code had
some issues:

> 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
> Fix For: 3.1
>
>
> 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.
