Hi,
i have some questions regarding bitmanipulations:
1. I found bitwise "and", "or" and "xor" operations, but as far as I
understand they are applicable only for modular types or packed boolean
arrays. Is this correct?
2. I did not found shift and rotate operations. Did I miss something or are
there really none?
3. When I want treat a value both as an integer and as a boolean array, how
can i do this? In pascal I would use a tagless record like
TYPE ov is record
case boolean of
true : i : integer;
false : byte_array;
end;
end;
Such overlay structures are not valid with Ada, so what do instead?
thanks
