Not sure why "without going through infinity" is relevant, but you can
always just use float("nan") to get one, and I'm sure there are other
calculations that result in nan. It's just that 0/0 (like any other
operation that involves division by zero, including 0**-1) immediately
raises, rather than silently returning a nan.
