"Unfortunately, a lot of calculators are going to truncate the results. However, if you manage to get a hold of one that doesn’t, solving 1/998001 will generate all the three digit numbers from 000 to 999. And in order, no less. I have no idea how this works, but it’s a pretty neat trick and even a bit unsettling. If you’re a fan of this kind of spooky math fun, solving 1/9801 will generate all the consecutive two digit numbers."
