This library is deprecated
Because I made a better one that does the same thing: exact.
The old README
cljs-numbers is currently a library for doing exact arithmetic (big-integers and ratios) in ClojureScript. No assumptions should be made about its performance or correctness.
Maybe in the future (if needed and wanted) it could include a full numeric tower.
Getting it
In the project.clj:
[com.gfredericks/cljs-numbers "0.1.2"]
Usage
The cljs-numbers.core namespace gives its own versions of most of the
core math functions. So if you want to use them nakedly, you'll have to
have a rather elaborate ns declaration to exclude the clojure.core
versions.
(ns foo.bar
(:refer-clojure :exclude [+ - * / = < > <= >= zero? pos? neg?])
(:require-macros [cljs-numbers.macros :refer [num-literals]])
(:require [cljs-numbers.core :refer [+ - * / = < > <= >= bigint bigint?
ratio? double? zero? pos? neg?]]
;; in case we need the normal stuff
[cljs.core :as cljs]))
(num-literals
(.log js/console (str (+ 84/7 4828948388888888888888838488441110N))))
TODO
- Look into extending compiler instead of
num-literals - Make string versions of Ratio and Integer look nice
Running Tests
Run lein cljsbuild once, then load tests.html in a browser.
