Actually, this is one thing I don't know. I don't know past the 100th decimal of pi. But I can assure you that the 100th decimal of pi is 9. So, if it rounds, then 9 becomes 0 and the 99th decimal increases.
To be more specific, the last 4 decimals of pi are 0679. So, if the 101st decimal is greater than 4, then 0679 turns into 0680. But I am pretty sure this won't happen.
Therefore, I am pretty sure that the 101st decimal of pi is lower than 5. Otherwise, the last two decimals before the 101st wouldn't be 7 and 9.
