Labels:text | screenshot | font OCR: If a certain computer can store only an eight-digit string (n=8), then the representation for the decimal fraction 0.2 will be stored as 0.11001100 x 2 4. What number is this, and what is the difference between this number and 0.2? Solution: 0.11001100 x 2 = (1/2 + 1/4 + 1/32 + 1/64) x (1/4) = 1/8 + 1/16 + 1/128 + 1/256 32 + 16 + 2 + 1 256 0.2- 51 = 1 . 51 256 - 5 256 256 - 255 = : 1 5 . 256 1280
