There are a huge pile of libraries for doing bignum, rational, fixed point, decimal, complex, vector, polynomial, symbolic, etc. math in Javascript. If you want you can even write one for 7-adic arithmetic, Eisenstein integers, numbers expressed in the golden ratio base, or points on the surface of a torus. There’s no language that can build in all possible number systems, and it’s not really the place of a language to try. It would be nice if JavaScript made a better type distinction between integers and floats though.
