In France, the comma and decimal point places are reversed when used in numbers (as contrasted from how they are used in the US).
For example, two thousand euros and fifty centièmes is written as 2.000,50.
This was difficult for me to get used to after moving to France. When I purchased my first laptop and tried using the French version of MS Excel, I wanted to throw the computer out the window! Not only do you have to get used to some letters being switched around and using a shift key to type numbers, but you need to reverse your commas and decimals.
