Can You Use Negative ASCII Values In Codes?

I recently came across a code that I'm interested in making.The code seems to either do one of two functions when applying the code: -[X] or -(X)
This means that my code is either doing the inverse of the absolute value of the value used or is doing the exact opposite of the X applied. The value is something I believe to be an ASCII Value write,and I was wondering if I can apply negative ASCII Values. Say I want to write negative 10,couldn't I just use This Value for my code: 2D313000?
It messes with the points lost from Killing Allies. I was wondering if I can make the ASCII Value negative,so it would have to do the opposite and give me a positive value?

Yes. You can use negative values by converting -10 or whatever. Also, try VERY big amounts:
99999999 -> 3939393939393939 (= 2 following addresses)

Alright,then that will be useful for the friendly fire code I recently released on here. I'd rather be gaining points from killing my allies than loosing them.
