There's a famous quote for this situation: "whatever goes up must come down." So halfway is 50%, half of that is 25%, again half it you have 12.5%, 6.25%, etc, eventually it rounds down to 0%, which is the ground. In this case gravity does the rounding for us.

 

 

 

I hope no one noticed I just copied most of the first post and then said it rounds down to 0.

 

 

 

then what number is 0% exactly half of?

Half of 0? I have no clue, i'm not a scientist. But If your hand is 100 and the floor is 0 100/0=0, so by that logic it hits the ground.
