Not automatically overflowing numbers is a Good Thing. For example: http://seclists.org/fulldisclosure/2010/Mar/447 Though the behavior now deviates from the java casting behavior where the more significant bits are just truncated. I can't think of many cases where a downcast is used *and* the original value is expected to ever be larger than the target type. If you really need that, then bit-masking prior to casting seems appropriate. On Mar 23, 7:41 am, Per Vognsen <per.vogn...@gmail.com> wrote: > Interesting.
