In the US gas prices at gas stations usually also show a tiny 9/10 of a cent in addition to the x.xx price, i.e. actual price is x.xx9 and I have never seen any other value for that 3rd decimal place

That 1/10th of a cent savings might have looked good when gasoline was 39.9 cents but it's a constantly shrinking share of the cost of a gallon of gas that might psychologically be making the number look bigger as it is more digits. But since everyone does it, no one has an advantage or disadvantage because of it. Maybe when gas gets above $10/gallon gas stations will decide it's better to drop the 9/10th than to purchase new signage and pumps that can handle an additional digit.
