I'm trying to go through EUDs a little further and want to know how to use negative values

I think very high numbers will be interpreted as negative values.

So how do i convert a negative value to a really high number then?

Numbers higher than a signed integer's max value will overflow into a negative number. You are limited to this number as the highest value (2147483647). If you enter a number higher than that, it will overflow and add the extra from -2147483648. An unsigned int's max value is something like 4294967295, so you can pretend that this is the highest value possible, even though it will read as -1.

What are you trying to do? Why do you need a negative value?

Edit: numbers were way off

Looking at game speed and want to try -1(i know to use eud actions)

I doubt that will work. Anyway, you can't directly enter the negative sign into SCMDraft, but you can copy/paste a negative number into it without a problem.

-1 is equal to 4294967295. If you add one to 4294967295 (or -1) you get 0. If you add -1 to 0 you get 4294967295.
0 and 4294967296 are the same number since 4294967296 does not fit into 32 bits.

The easiest way to convert negative numbers to unsigned numbers is to put the negative number into windows calculator (scientific mode) and hit the Hex button, hit Dword, then switch back to Dec.
The range of signed numbers is -2147483648 to 2147483647.

Math between signed and unsigned numbers is exactly the same, they are treated the same.

Any game speed value that isn't 0-7 will be an overflow/underflow itself, since that's not actually the speed, but a speed index.

Actually, there's a trick that will make SCMD2 give you a negative sign...in Classic Trigedit, if you just hold down the "9" key until the field fills up, it'll turn into -1 when you hit enter. This gives you a functioning negative sign that you can use to input a negative number (or copy to the clipboard in order to put somewhere else).

Very handy when making a trigger for adding negative minerals/score-- which you might want to do because, unlike subtracting, adding a negative can result in a negative quantity. But that's besides the point...

You are just full of useful information, this is a trick I wasn't aware of Thanks for throwing that out there.

yea, that trick is going to simplify balancing math

Thats a very nice trick xD, I never knew adding a negative number would actually end up bringing it below 0.
