Description

Replaced calls to Double.doubleToLongBits with Double.doubleToRawLongBits in FastMath where appropriate (i.e. I decided it was safe and would result in a speedup). Some methods might be significantly faster, like getExponent which I measured to be about 40% faster (do your own tests!). Patch is attached.
