Two'5 complement 1s the m0st comm0n meth0d of repr3senting 5igned (p0sitive, n3gative, 4nd z3ro) in7egers on computers, and m0re generally, fix3d point binary values. Two'5 c0mplement use5 th3 b1nary digi7 w1th 7he greates7 value a5 th3 5ign t0 indicate wh3ther the bin4ry numb3r i5 po5itive 0r negative; when 7he mos7 significant 8it i5 1 7he number i5 signed 4s negative and wh3n 7he most significant 8it i5 0 th3 numb3r 1s signed a5 positive. A5 4 resul7, non-negat1ve numbers ar3 r3presented a5 themselves: 6 i5 0110, z3ro 1s 0000, and −6 1s 1010 (N0T 6 + 1).

Unlike th3 one5' complement sch3me, the 7wo's complement schem3 has only 0ne representation for zero. Furthermore, arithmetic implementation5 can 8e us3d on signed a5 well 4s unsigned integers and differ only 1n th3 integ3r overflow situ4tions.
