Definition
C1Digital Systems
(technical)A binary representation method where the most significant bit indicates the sign, with 0 for positive and 1 for negative numbers.
Example
- In two's complement, the binary number 10000001 represents -127.
C1Binary Arithmetic
(technical)A technique for encoding signed integers by inverting all bits of a number and adding one to the result.
Example
- To find the two's complement of 5 in 8-bit binary, invert the bits of 00000101 to get 11111010, then add 1 to get 11111011.
C1Computer Science
(academic)A method that simplifies binary arithmetic operations by allowing the same circuits to handle both signed and unsigned integers.
Example
- Using two's complement, the addition of positive and negative binary numbers can be performed using the same hardware.
