4b*1 for money...probably also for HP. But you can just lolspam everything, so what difference does it make?

Not much, but if anyone is interested:   HP = double*1

Interestingly enough, Judgment City, which is supposed to have an INFINITE amount of HP's, does not.  So it can actually be beaten.  It starts out with a total of 2147483647 HP's, which slowly decline under attack (or quickly through C/E "adjustment").

Actually, that's not weird at all. Integers are stored in computers using 32 bits, therefore you have a total of 2^32 possible numbers. As you need to represent negative numbers as well, half of these possibilities is for negative numbers and the other half is for positive ones. If you do the math, this means the highest positive integer you can represent(without using long and other computer "tweaks") is 2^32/2 - 1(0 counts as a positive number)
