I don't think it's the best way to represent it since it can't exist. The best way to represent it, honestly, may be through " an unidentifiable number". Because the point is that you can't have a one on the end of an infinite number of 0s. That isn't just an undefinable number, that's also an impossible number since it doesn't make mathematical sense - so I think to use it as an undefinable number would be silly :p
