Changing negative integer variables to positive

[Valtarian]

Hello
I have a bank integer variable that is arrayed for each of the six players on the map. It is used to hold gold past the 1M limit.

For some reason, once the bank integer reaches in the hundred millions/billions, it automatically switches to a negative integer.

Is there a way I can keep an integer positive?

Thanks!

Hold it as a string.

Another way of doing this, is to use the BigInt system by Nestharus.

The reason you are seeing your values go negative, is because you are 'overflowing' the integer type. It has a maximum/minimum value, and it is signed. In a typical language, the way to get around this is to use a larger datatype such as an unsigned long, or coding a new type yourself. Warcraft III has none of these.
