Thomas Neidhart commented on MATH-901:
--------------------------------------
I did some more tests with jodk and they look very promising, e.g. log and
log10 are *much* faster than the current implementation in commons-math (which
is known to be slow, see also
http://blog.juma.me.uk/2011/02/23/performance-of-fastmath-from-commons-math/).
> FastMath.sin is slow
> --------------------

> The FastMath.sin (maybe other functions too) are not nearly as fast as some
> other libraries that can be found on the internet.
> The *much* faster code can be found here

> Max Absolute Error Apache vs JDK: 1.1102230246251565E-16
