And, although the spaces are based on integer values, processing is done with floating point numbers.

In processors like RPP, Rawtheraee, and PhotoNinja, yes.  In ACR/PS, I don't think so.  Adobe still uses integer arithmetic as far as I know.  But I'd certainly be willing to be guided to documentation that says otherwise.

I would be surprised if it were otherwise. It is standard practice to map 0-255 to 0-1, it is just much easier to algorithmically process that way.

Surprise is indeed fun. But I'm waiting for documentation that supports the surprise.

Meanwhile normalizations do not require floating point.
