[Javascript] INCREDIBLE IE BUG!!!!

[Chris Basken]

Yes.  When I worked on an accounting page, I was informed by the client's
bank that internally they convert all money to the lowest possible
demonination (pennies, for American currency, for example), do the math like
that, then convert back.

So you may have $500.00 in your checking account, but the bank sees it as
50,000¢.
