Unsigned representation An unsigned integer is an integer that can never be negative and can take only 0 or positive values. Its range is between 0 and positive infinity. An input device stores an unsigned integer using the following steps: 1. The integer is changed to binary. 2. If the number of bits is less than n, 0s are added to the left. 3.12
Example 3.1 Store 7 in an 8-bit memory location using unsigned representation. <strong>Solution</strong> First change the integer to binary, (111) 2. Add five 0s to make a total of eight bits, (00000111) 2. The integer is stored in the memory location. Note that the subscript 2 is used to emphasize that the integer is binary, but the subscript is not stored in the computer. 3.13
