Well, the algorithms are documented. They're in your proposal. I didn't
put them in my documentation because I was worried that if I changed
them in the future (and I don't mean the near future, I'm going to be
very cautious about such changes), that there would be complaints
because I'd changed from what was in my documentation.

But I have changed my mind on this (as I mentioned earlier). Although,
I'm still not sure if it's appropriate to fully specify the functions
for integers.

It wasn't, I was just trying to give some background on discussions that
had happened off list.
