So what you're saying is if you change the base from say 10 to 2, then you end up with a whole other interesting problem. So once again we have to look at what the numbers are being used for. In general 0.9999999... approximates 1, however under special circumstances it may not be adequate, so what are those circumstances exactly, and there you would have a problem that Calculus probably couldn't solve. Thanks for pointing that out.
