WebIn the sign-magnitude representation method, a number is represented in its binary form. The most significant bit (MSB) represents the sign. A 1 in the MSB bit position denotes a negative number; a 0 denotes a positive number. The remaining n −1 bits are preserved and represent the magnitude of the number. WebThe sign-magnitude representation of a binary number is a simple method to use and understand for representing signed binary numbers, as we use this system all the time with normal decimal (base 10) numbers in …
