Round to even is ambiguously defined.

[nmichaels]

The description in rounding.html of the "Round to Even" method is confusingly worded. The "it" referenced in "...increase the digit only if it's not even" is ambiguous. I would rewrite that sentence, after looking up the method in Wikipedia, as "If it is equal to half the base, pick the direction that yields an even number."

I've decided to change it to "increase the digit only if that produces an even result"

That works for me.
