If you want to go to the Vatican Museums (home of, among other things, the Sistine Chapel) you can buy your tickets in advance online. During the checkout process they list the number of Euros you owe, but they also include a few leading zeros. Having a computer that allows room for all the digits you might need is a good thing, as anyone who remembers the whole Y2K thing realizes. So kudos to Vatican City for making sure that no transaction will be too large for the checkout system to manage. But seriously, just how much money did they expect people to spend in those online transactions???
