Arithmetic is a relatively self-contained part of a language. The problem isn't that JavaScript's arithmetic is lame, it's that they didn't leave any way for the programmer to fix it—even if you make rational bignums out of arrays of doubles (or whatever), you can't make them drop-in replacements by overloading operators. It's a strange oversight for a language which lets instances override methods.
