Math.exact vs. ExactMath

[Gilles Duboscq]

Hello,

I think the plan is to move to the Java 8 methods and deprecate/remove
the ExactMath methods that now have an equivalent in Java 8.
I don't really know when this will be done though.

At least a simple summation loop using addExact() was about 40% slower using Math instead of ExactMath.
