Not entirely sure I'm posting this in the right place, but it looks like it...
This is a patch to optimize BigInteger.doubleValue() and floatValue(), which are both currently implemented by converting to a string and back. Doing it with bit-twiddling and Double.longBitsToDouble improves the speed of those methods by something like two orders of magnitude in my benchmarks.
