According to the documentationConvertCheckedwill throw when an overflow occurs, i.e. converting a number larger thanbyte.MaxValue(255) or smaller thanbyte.MinValue(0) to typebyte– similarly all other numeric types.

Yes, numeric overflow makes a difference. So it applies to unboxed numeric types only/strictly?

You can only unbox to the exact type anyway (aside from lifting of nullables), e.g.object boxed = 1; long unboxed = (long)boxed;is an invalid operation. But yes checked only applies to type conversions to an numeric or rather to an integral type, see also the documentation of the checked keyword.
