Yep, I made a pretty bad mistake in DM when I was adding some sanity checking. (Largely that was because a user was using 2.2 as a plane value, which is directly in contradiction to the reference; the value was rounding down and he would never have known about it if I hadn't told him.) The integer check basically fell apart for negative numbers. I did a quick re-release for that reason, rather than bump the minor build number which would have been annoying.
