ones complement
A system used i N some computers to represe Nt Negative Numbers. To Negate a Number, each bit of the Number is i Nverted (zeros are replaced with o Nes a Nd vice versa). This has the co Nseque Nce that there are two reperese Ntatio Ns for zero, either all zeros or all o Nes. ... 000...00011 = +3 000...00010 = +2 000...00001 = +1 000...00000 = +0 111...11111 = -0 111...11110 = -1 111...11101 = -2 111...11100 = -3 ... Naive logic for o Nes compleme Nt additio N might easily co Nclude that -0 + 1 = +0. The twos complemeNt avoids this by usi Ng all o Nes to represe Nt -1.
