Jul 30, 2019 · When the number is negative, the sign is represented by 1 but the rest of the number may be represented in one of three possible ways: Sign-Magnitude method, 1’s Complement method, and 2’s complement method. These are explained as following below. 1. Signed Magnitude Method: In this method, number is divided into two parts: Sign bit and …

Usually we represent a negative decimal number by placing a minus sign directly to the left of the most significant digit, just as in the example above, with -5. However, the whole purpose of using binary notation is for constructing on/off circuits that can represent bit values in terms of voltage (2 alternative values: either “high” or “low”).

In binary, we normally represent binary numbers in two’s complement. It is a technique that simplifies calculations when working with negative numbers (although it is somewhat more complicated for humans to understand).

There are two common ways to represent negative numbers within the computer. Remember, the minus sign does not exist. The computer world is made up entirely of zeros (0) and ones (1). These two techniques are called signed magnitude representation and two’s complement. Let’s explore sign-magnitude representation first.
