Interpret 11011011 as a two's complement binary number, and give its decimal equivalent. First, note that the number is negative, since it starts with a 1. Change the sign to get the magnitude of the number. Convert the magnitude to decimal: 001001012 = 2516 = 2Ã16 + 5 = 3710.
The complement of a number is another number in which each digit, when added to the corresponding digit in the original number, will add up to the largest digit of the base in which the number is expressed.That sounds far more complicated than it really is. It's easier to understand by working through it.n other words, each digit, added to it's corresponding digit in the complement, should total 9. So the complement of 1976 would be 8023. Perhaps a better example would be the number 9876543210. It's complement would be 0123456789.
