Does 0.00000000000000000000000000000000000000000000000000000 repeating exist?

@helenS Does even my age repeat as a decimal?
What about 0.79797979797979... or 79.00000000000000...

@TheOrionbeltseeker Haha! 😁

@Tennessee2 ... same as above; these ever-repeating numbers represent the limit of a series, and that limit is always a well-defined real number.

In fact these series are the core of constructing reals. If you are interested in the theoretical background, google "Dedekind cut".
