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: https://i.stack.imgur.com/FOYDt.jpg https://i.stack.imgur.com/rZyAT.jpg

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

You're exceeding the maximum "safe integer" size of an IEEE floating-point number. Your best bet is probably to represent the IDs as strings. – Pointy Aug 30 '20 at 15:11

Consider using BigINTs instead? `76561198272848927n === 76561198272848930n // false` – evolutionxbox Aug 30 '20 at 15:13

These are IDs, not numbers. Don't convert them to numbers, use the strings! – Thomas Aug 30 '20 at 15:17
