Since the Mt.Gox engine seems to not have been validated, has anyone tried anything like putting a negative number in the sell price? Or a negative number of coins to sell?
I wonder what kind of havoc that would cause if it isn't cleaned up.
Another thing they need to test for is very large integers. If they mixed signed and unsigned numbers in any stage of their process, a very large integer will be interpereted as a negative number, even though it wasn't negative in the input box.
Maybe Mark should look into this...
