Ah, actually the documentation begged to differ. Well checking for a zero

numerator is stupid because the math just works, so we'll keep the new behavior
and change the documentation because I'm tired of seeing giant div0 exceptions
in the logs and the fix will no doubt to be to find those places and change
them to display zero if the denominator is zero which is exactly what we're
doing here anyway. It's the new math.
