Integer conversion equation on both sides at the same time divided by 2, a0 is the least significant bit of the data obtained in order to push on, so turn binary decimal integer result is the lowest vertical position at the top
Fractional conversion equation is multiplied by 2 at the same time on both sides, that is, the data a1 and the first one decimal place, this pushing on, it is transferred binary decimal result is highest vertical uppermost
