Negative integers?

[tomshreds]

Hi,

I was wondering, I need my in-game balance to go negative at some times in my game.

How could I do this? I'd like to be able to have a balance of -1450 for example. And then earn some money and go positive, etc.

Any idea?

Thanks!

So...where's the problem?

Code: Select all

local balance = 10;
balance = balance - 100;
print(balance);
balance = balance + 200;
print(balance);

Frankly, I was sure lua wasn't going to do this. So sure that I didn't tested it.

Thanks for this and sorry :-S

I'm really interested in what led you to that belief. Do you know why, or just have a good guess about it?

I think that every single programming language ever has supported negative numbers.

Some languages also support unsigned number types;
Some of RISC architectures may leave signed number implementation to programmer for various reasons.
