Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, [1] and more generally, fixed point binary values. Two's complement uses the binary digit with the greatest value as the sign to indicate whether the binary number is positive or negative; when the most significant bit is 1 the number is signed as negative and when the most ...
For example, adjusting the volume level of a sound signal can result in overflow, and saturation causes significantly less distortion to the sound than wrap-around. In the words of researchers G. A. Constantinides et al.: [1] When adding two numbers using two's complement representation, overflow results in a "wrap-around" phenomenon.
The nines' complement plus one is known as the tens' complement. The method of complements can be extended to other number bases ; in particular, it is used on most digital computers to perform subtraction, represent negative numbers in base 2 or binary arithmetic and test overflow in calculation. [1]
Addition of a pair of two's-complement integers is the same as addition of a pair of unsigned numbers (except for detection of overflow, if that is done); the same is true for subtraction and even for N lowest significant bits of a product (value of multiplication). For instance, a two's-complement addition of 127 and −128 gives the same ...
Overflow cannot occur when the sign of two addition operands are different (or the sign of two subtraction operands are the same). [1] When binary values are interpreted as unsigned numbers, the overflow flag is meaningless and normally ignored. One of the advantages of two's complement arithmetic is that the addition and subtraction operations ...
The carry signal represents an overflow into the next digit of a multi-digit addition. The value of the sum is 2 C + S {\displaystyle 2C+S} . The simplest half-adder design, pictured on the right, incorporates an XOR gate for S {\displaystyle S} and an AND gate for C {\displaystyle C} .

The two's complement by definition is used only for binary numbers (since the term is derived from ones' complement), and only for integers. Certainly you can generalize it for other positional numeral systems, you can do it in several ways, and not necessarily for even radices.
