After some x length of time, the charge in the capacitor went down to 0.1e-17[mV]. After writing the answer on the board, my professor turned to the class, pointed at it, and said "What's this number?" We said "That's one times ten to the negative 18 millivolts" when he interupted us and said "Wrong! The answer is zero. If you can't accept that 0.1e-17[mV] is equal to zero, you need to change your major to math right now, or you will hate the rest of your career."
