Currently anything smaller than the Planck length is indefinable.(1.6X10^-33cm)

Bert, the question here is pure mathematics question, doesn't really have any relation to the physical universe. It's quite easy to write down or do arithmetic with numbers smaller than the planck constant :-)
I think the issue here is that 9.999... and 0.999... are both non-rational numbers, and do not obey the normal rules of arithmetic, so it's invalid to subtract them like that.
