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. Web• Representing real numbers in a computer always involves an approximation and a potential loss of signiﬁcant digits. • Testing for the equality of two real numbers is not a realistic way to think when dealing with the numbers in a computer.
