This is not the most interesting script in the world, I made it to practice while loops that I absolutely sucked at and see what funky things happen.

This script does nothing if you put in mainNumber = 1 for obvious reasons, but if you put in 2-21 it will evaluate to 21.99999999999999, 22 evaluates to 22 1000 times, and mainNumber = 23 or higher evaluates to 22.00000000000001.

I have not found a whole number that doesn’t follow this pattern yet (Truthfully haven’t dug as far as I would like) but it is interesting how this little practice script did something like this when I was just messing around.
