---------------------------------------
I am not sure what sql standard says for such scenarios, but atleast mysql
instead of throwing exceptions does correct math and returns valid results to
users.
> Overflow, Underflow errors

> With very large (or very small) integer values there is a possibility of
> overflow (or underflow) errors. Worse thing is instead of failing, this
> currently results in incorrect results being returned, thereby leaving user
> with no clue that some of the tuples may have wrong value.
