WebApr 4, 2013 · In the extreme case, you could always convert a one's complement by looking if the most significant bit is 1. If it is, you set it to 0, invert all the bits ~ and then increment the result by one. If the most significant bit was 0, you already have a two's complement (as both are equivalent, when positive) – Nolonar Apr 4, 2013 at 14:38
