see the bitwise-features in INTEGER_GENERAL, e. g. bit_xor:

class XOR

create {}
   make

feature {}
   make
      local
         a: INTEGER
         b: INTEGER
      do
         a := 0xFF
         b := 0xAA
         a := a.bit_xor(b)
         io.put_string("A = " + a.out)
      end

end


For bitwise AND, OR and NOT even the well known pre/infix operators "&  
| and ~" are available.
