So it's "twos complement" to negate a number you invert all the bit then add one. The fun part of 2's complement is when you count in binary from -1 to +1 -1 = 1111 0 = 0000 +1 = 0001 The sign bit flips and all you need is a simple ripple counter. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
