Typo: parameter

Doesn't this skip the very last item in the first pass? Is that ok?

I was thinking that would be ok, since our new float will always be the last one on the list the way that the code is currently used, but I should be paranoid and not skip the last one just in case I'm missing something.

Somebody should teach the commit-queue to figure out the reviewer's name at these straightforward cases.
