It isn't phrased as a fallacy, it's phrased as an argument against using a float. There's obviously some difference of opinion about what "below two decimal points" means. Given that they point out the 0 decimal point Yen, it seems they mean "more precise than", ie more decimal points. Even if they meant the opposite their own example of the yen disproves that.
