Step 1 of 2 2.017E Consider a 8 bit binary number (In decimal value is -25) and its negative value is Steps for finding out two's complements are as follows, 11100110, Complement bits 1+ 11100111, Thus the two's complement of 8 bit binary number is given by 11100111, and in decimal -25. Hence an 8-bit binary number is having same negative value when interpret either a decimal or two's complement number. Step 2 of 2 Similarly consider a 8 bit binary number 01111000, (In decimal value is +120) and its negative value is Steps for finding out two's complements are as follows, Complement bits 10000111, 1+ = Thus the two's complement of 8 bit binary number 01111000, is given by 10001000, and in decimal -120. Hence an 8-bit binary number is having same negative value when interpret either a decimal or two's complement number.
