Hmmm. I do think the last sentence belongs to the next paragraph. The
identity of the author does not change my opinion on that point:-) If you
have another argument, maybe.

I doubt that IEEE floating point rounding rules are likely to change much,
so referencing the latest version is both safe & cleaner. Also, wikipedia
would change its implementation from php to something else (well,
unlikely, probably as unlikely as a change in IEEE fp rounding rules:-).
