Not OP, but I used Google's Long.js (among other things) in a project[0] to get around the limitation of not being able to do as in Python:

    import fractions
    print str(fractions.Fraction.from_float(0.3333).limit_denominator(10))

Almost anything that compiles to JS would be better than by-hand JS; I'd love to use ClojureScript with re-frame at work...
