[Console] CvarAdd command

[D2JK]

I'd like to suggest a new console command: CvarAdd. The command would add the given value to the given console variable.

Usage: CvarAdd <CvarName> <Value>

Examples:

CvarAdd Mouse_Sensitivity .01
CvarAdd FoV -5
Bind mwheelup CvarAdd MyVariable 4
Bind mwheeldown CvarAdd MyVariable -4

The mouse wheel bind example illustrates how this would be useful for mod developers trying to get something to look or positioned just right (utilizing the GetCvar() command).

Isn't the 'eval' CCMD sufficient?

It's unwieldy as hell, and sometimes I couldn't get it to work at all.

Ah. I tried to look if a command like this already exists, but I missed this functionality in "eval". Eval seems more powerful as well. I wish someone had mentioned this when I asked in the "How do I" thread.

But now, while reading up the following table of eval expressions, I was also amazed to find out something: the console can not only compute exponentiation, it can do this even with non-integer exponents! Yet we don't seem to have a generic exponentiation functionality as a Decorate expression. Why is this?

The above question was left unanswered, so should I make a dedicated feature request for it then?
