Not sure if I am in the correct place on this forum but this is the nearest area I could find.
Basically I have one question regarding converting binary numbers to two's complement negative binary numbers.
From what I have read you add a 1 if it's negative after inverting all the numbers. What if there is already a 1 at the beginning. Do you move to the next 0 and change it to a 1 to negate it?
