And for casting them to "bigger" types (also implicitly when doing operation between them and a "bigger" partner) the obvious way is sign-extension (i.e. duplicate highest order bit i.e. "sign" bit) for signed types and zero-extend unsigned types. As the extend operation is not allowed to change the value, it's obvious that for a 1 bit signed type the possible values are 0 and -1.
This is what I tried to show with the example. -Michael ------------------------------------------------------------------------------ Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.
