According to market practice, the price of foreign exchange rates is usually composed of five significant figures, counting from the right to the left. The first one is called "X points," which is the smallest unit that constitutes exchange rate changes; the second is called "X Ten points," and so on.

For example:

1 euro = 1.1011 US dollars;

1 US dollar = 120.55 JPY

The euro against the U.S. dollar changed from 1.1010 to 1.1015, saying that the euro rose by 5 points against the U.S. dollar.

The dollar against the yen changed from 120.50 to 120.00, saying that the dollar fell 50 points against the JPY.
