When writing an amount of money, do you have the habit of always writing two digits after decimal point?

I don't know if this is just a good habit to have, or I'm being pedantic. Actually it's probably the latter.

But i think it's just sloppy for people who text like "you owe me 13.2 / 13,2 for the ticket". I can't intuitively understand that you are talking about an amount of money. Since the € symbol is normally after the amount, it helps a little. But most people don't use the symbol at all.
