Basically your making number big enough to hold the output.  You don't
need to keep track of the max size. If it got truncated, it would be
wrong anyway and the program may crash in a less obvious way. I'd say
do this: Find out the minimum required size for number to make WoW not
crash, and round up to the nearest 10's. Like your test required 91,
make number 100. Hopefully we only need to do this once, and looking
at the code, I'm sure that windows has a limitation like this
somewhere too.
