My actual suggestion was that a question mark could signal that the previous digit might be wrong by +/- 1. Using "last unquestionable digit" or "first questionable digit" is not good, because [0.999999999 .. 1.000000001] has no unquestionable digits. With my proposal, this would be 1.000000000?, and [-0.001 .. 0.001] would be 0.000?.
