Well, then try to calculate the German VAT with "integers": 2345 * 1.19 -> 2790.5499999999997 Ah, we have to round the result: (2345 * 1.19).toFixed(0) -> 2791 Or: (23.45 * 1.19).toFixed(2) -> 27.91 Hm, same result (but see <http://www.jibbering.com/faq/#formatNumber> for very old browsers). Anyway, you can't do arbitrary monetary calculations reliably with IEEE 754 doubles. However, that is the only number type that is guaranteed to be supported by conforming ECMAScript implementations. -- Christoph M. Becker
