I do not understand why the last sentence in the first paragraph about
bitwise ops is put there with rounding issues, which seem unrelated. It
seems to me that it belongs to the second paragraph which is about
bitwise operators.
That's the part which came from Josh Berkus. We discussed this patch on IRC.
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.
The wikipedia link can be simplified to a much cleaner:
http://en.wikipedia.org/wiki/IEEE_floating_point#Rounding_rules
It can, but then you always refer to the latest version of the Wikipedia
page, which might or might not be a good idea. The link in the patch points
to the current version from yesterday, no matter how many changes are
introduced afterwards.
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:-).
