Um, yes? That's implicit in the question -- and generally the numeral system in
question is implied to be 10. Context is important.
But for what it's worth, if you take a random number from the Reals, then the
answer will be "infinite digits" for Almost All numbers, no matter what
number base you are using.
A harder question is, what if you take a random number from the Integers? How
many digits will it have in (say) base 10? I don't have a good answer to that.
I think it may be ill-defined.
