Does 1,9999...=2?

What about 0,4999...=0,5 or 0,00...(infinite zeroes)...1 = 0?

OK a bit of a side track here but honest question here.  Why does one of the posters above expressly refer to 1.999.. as a series?  I can kind of see the logic to that but it strikes me odd as when I was in school, series always refered to a serires of terms in the summation or product of some sequence or set, not the actual sum or product.

Is it the current education trend to view irrationals as a summation or is it just the guy above?
