I just wonder that if 'Same' occurs ...how to express area ? 0.00 ?

and after 'Same' ... all cases should be 0.00 ... right ?

plz.. give me more test case, thx

Yes when you see 'Same' it means that the space is just a line and therefor it`s area is 0.00

Hi!
Actually, there is a special case : when you don't move (you updated position is the same than your last position), the area should not change.
