Will calculate e to infinity if left on forever. Scratch is slow, sorry. Press e to input your own exponent if you don't want it to slowly calculate several exponents.
I figured out that the formula for e is (1+1/infinity)^infinity, so I created a Scratch program to calculate e using the formula. It doesn't make any sense, because this will take years to reach 1,000 digits, which you could just search for online, thanks to a super computer.
