If is expressed in binary form, what is the digit in the 19 places to the right of the binary point? Dan Heflin
Well, how do we do this? • You take the (4/7), and multiple by 2 to get 1.1428 • You take the whole number representation, which is 1 in this case. This number then becomes the first binary point to the right of the decimal. • So as of now, we have .1
Continue this process • Well, before we continue, we must disregard the whole number in front. So, we have .1428, not 1.1428. • Then .1428 x 2 = 0.2856. So, we take the 0 and that is our next binary point. • So now, we have .10?????????
Even more • So we continue to get 0.57142, so our number is now .100 • Then we get 1.1428, so now our number is .1001 • But wait! 1.1428 is the same number we started with! So this is a repeating decimal! • So our number is .1001001001001001001001001001001001001001001001001001001001001001 and so on.
Back to the question • We were asked to find the point in the 19th place. So • .1001001001001001001001001001001001001001001001001001001001001001 • So our answer is: 1
