Ah, yes. When Python 2 -> Python 3 changed the meaning of / the
meaning of % got tied instead to //. But if you think about it, with
the floating-point result you're describing there, it simply makes no
sense to even ask what the remainder is. So, if you're going to use %,
use //, and then it all makes sense.
