Why would you not use "checked"?

[Brett]

Why would you not want to use checked on any type of mathematical operation?

Or use unchecked for that matter?

Thanks,
Brett

Why would you not want to use checked on any type of mathematical
operation?

There are some algorithms that actually use the overflow (rely on it to
happen). I think I've seen this done in an integer random number generator.

In addition to which, I believe unchecked operation can be
significantly faster - it could make a huge difference in an app which
is heavy on calculations.

Unchecked effectively does a modulus operation for free. This is
useful in some mathematical applications.
