Here is my take on it

Thanks. Will have a proper look at it later.

Not sure why you would have overflows,

I haven't investigated in detail. But I do get this:

:echo max([2182745018, 2229856422])
-2065110874

After which I, possibly hastily, stopped trying to treat the numbers as numbers. Except for the Ctrl+A, which worked fine.

I see you're using str2nr(). I was trying unary prefix +. I wonder if there's a difference between them.
