Like the decimal system each digit in the binary system represents a value, but these values are based on the power of 2. The first digit left of the decimal point in the binary number system would is 20 which equals 1. Each position continuing on to the represents a higher value or power of 2.

Going to the right is a little different. The first position to the right of the decimal point is 2-1 which equals ½, then 2-2 = 1/4, 2-3 = 1/8, 2-4 = 1/16 and so on.
