That's because numbers are floating-points numbers; you'll find this in all languages/platforms whose types follow IEEE 754 Floating-points Arithmetics (Java/JVM, JS, C, .NET, etc.) that is, almost everywhere. Java has BigDecimal if you need precision; it's emulated in GWT but performs much slower than doubles, which just map to JS numbers.
