I want to ask that we say 0.999...=1 because the 1 is the least upper bound (supremum) of 0.999... or are they exactly same numbers.(adsbygoogle = window.adsbygoogle || []).push({});

I ask this because i am confused with finding (the infimum) the largest lower bound of 1. Do you think it should be 0.999... or is 0.999...=1.

Thanks for your comments...
