If anything I was thinking of recording the remainder in the the original
number object, not the one returned (or possibly in something like a WeakMap
keyed to it). So it does increase state and makes it technically no longer
immutable, but that change in state would not be detectable from outside except
by profiling performance. It's state that would have to be ignored in the
equality check.
