Kaksinkomplementtina refers to the two's complement representation, a standard method for encoding signed integers in computing. It is the most common way to represent negative numbers on computers. In this system, a positive number is represented by its standard binary form. To find the two's complement representation of a negative number, one first takes the binary representation of its absolute value, inverts all the bits (changes 0s to 1s and 1s to 0s), and then adds 1 to the result. The most significant bit in a two's complement system typically indicates the sign, with 0 representing a positive number and 1 representing a negative number. This representation simplifies arithmetic operations, particularly subtraction, as it can be performed using addition circuits. For example, subtracting a number is equivalent to adding its two's complement. The range of representable numbers in a two's complement system depends on the number of bits used. With n bits, the range is typically from -2^(n-1) to 2^(n-1) - 1. This method ensures that zero has a unique representation and that addition and subtraction operations are consistent for both positive and negative numbers.
