Padding doesn't count...

• JadeNB 11y ago
  Well, to be sure, one can say that it does count or that it doesn't—the axioms of mathematics are only as humans make them. I was arguing why it might make sense to have it count. Another reason that it might be a good reason to have it count: by my definition, I can say "the decimal expansion of a number eventually repeats if and only if the binary expansion of that number eventually repeats." This becomes considerably more awkward if you don't consider a terminating expansion as consisting of eventually repeating 0's; for example, 1/5 has a terminating decimal expansion 0.2 but an immediately-repeating binary expansion 0.repeat(0011).
