That is what message threads do. > So you say a single bit can be signed? Yep. The highest order bit in a number in the "2's complement" encoding is the sign bit. > No. Show me an ALU that calculates with signed bits. How does it determine > whether a "1" is positive or negative? Not at all. (Please do read more about "2's complement" encoding. ) When adding or subtracting, the ALU does not care about the type being signed or unsigned. The resulting bits are the same. (i.e. the resulting status Bits also are the same in the ALU, the compiler only interprets them according to the type of the result if it needs to take care of the potential sign of the result. ) -Michael ------------------------------------------------------------------------------ Shape the Mobile Experience: Free Subscription Software experts and developers: Be at the forefront of tech innovation.
