[math] break up MathUtils?
I agree with Gilles' recent comment that this class is bloated. Any ideas on how to break it up? Now would be a good time to so it.

I think Gilles is on the mark here.
+1 For the break up
+1 For organizing along conceptual lines.

I'd rather divide it along conceptual lines. E.g.
Arithmetics (for "addAndCheck")
Precision (for "equals", "compare")
Binomial (for "binomialCoefficient")
MathArrays (for "linearCombination", "distance", "safeNorm", ...)
Function (for "pow", "cosh", ...) [But maybe those should go in FastMath].
Best regards,
Gilles

One way would be to divide it into DiscreteUtils (int's and long's)
and ContinuousUtils (float's and double's).
Cheers, Mikkel.
