Flag restarts everything. Both ways can handle decimals, but if you value your computer don't do degrees-to-radians with decimals too much. It will take (exponentially buh-dum-ching) longer the more decimal places there are. If you want to see why these are true, try it with the "180" list open. Final value subtracts 360°/2π until it is less than 360°/2π.
Bored at home If I ever redo this I'm gonna watch a video on how to turn decimals into fractions because I did it myself in the most inefficient way possible.
