ones complement
A system used in some computers to represent neg ATive numbers. To neg ATe a number, each bit of the number is inverted (zeros are replaced with ones and vice versa). This has the consequence th AT there are two reperesent ATions for zero, either all zeros or all ones. ... 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 ones complement addition might easily conclude th AT -0 + 1 = +0. The twos complement avoids this by using all ones to represent -1.
