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

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 [url=https://zdoom.org/wiki/DECORATE_expressions]Decorate expression[/url]. Why is this?

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

Isn't the 'eval' CCMD sufficient?

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:

[i]CvarAdd Mouse_Sensitivity .01
CvarAdd FoV -5
Bind mwheelup CvarAdd MyVariable 4
Bind mwheeldown CvarAdd MyVariable -4
[/i]
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).
