While it appears to improve conformance with the IEEE Std 1003.1 and
expand the range of numbers which are correctly handled, it does
more calculations. I wouldn't want to see it get in without
performance testing and confirmation that existing apps don't rely
on the non-standard behavior. I don't remember either of those
happening.
