Cause: The problem was that the logic for lte/gte depended on the fact that lte is equivalent to !gt.
However, in Java, this assumption is invalid - any comparison involving NaN always yields false.
Solution: The fix was to adding lte and gte methods to Numbers.Ops directly, rather than implementing everything in terms of lt. This was the only fix I could see that didn't incur the cost of runtime checks for NaN.
