I don't see how it would be significantly different in other bases. In hexadecimal it'd be 0x0.ffff.. * 0x10 = 0xf.fff..

The rules are essentially the same.

Oh right! My mistake. Was stuck in my head with "10 == nine plus one" instead of your insight, multiply by '10' in whatever base.

Anyway it's still an artifact of representation. If rationals were represented as fractions, then it is unrepresentable. 1/1 X 10 == 10/1?
