I currently try my best with the SteamAPI, for that I need the Profile-IDs. I tried out with my own, but somehow js changes the id.
EG:

My ID is 76561198272848927, but JS somehow always change the last two digits from 27 to 30. Why? And how do I fix this?

Strangely enough, when I try to add "9333852702227980 + 7", it returns me "9333852702227988" and not "9333852702227987".
I cannot figure out why! Any ideas and how to go around this problem?
alert((9333852702227980 + 7).toString());
