The yen is the one currency on this page with no subunit in everyday use. ISO 4217 records zero decimal places for it, so a price in yen is a whole number, and a yen figure with two decimals is almost always the trace of a conversion that nobody rounded. The pair is quoted as yen per dollar, which makes the number large and a misplaced decimal easy to miss.

Is this rate published or calculated?
Calculated. Our source publishes how many dollars and how many yen one euro buys, and this page divides the second by the first. Both figures are taken at the same moment on the same day, so the cross is coherent, but it carries the rounding of both.
