Question

Convot the following biliary number into decimal form using any method ? (1010.100)2

Answer 1

Answer:

10.5

Explanation:

1010.1

Handy method you can find searching google images, and I originally learned

from some guy teaching an online java course.

.1 --> 1 * 2^(-1) = 0.5

0 --> 0 * 2^(0) = 0

1 --> 1 * 2^(1) = 2

0 --> 0 * 2^(2) = 0

1 --> 1 * 2^(3) = 8

0.5 + 2 + 8 = 10.5

If for some reason it isn't very clear, just take the number, (x) and multiply it

by two to the power of the position it is in. (e.g. first number before decimal point is 0, second 1, etc).
