accounting.js is a tiny JavaScript library for number, money and currency parsing/formatting. It's lightweight, fully localisable, has no dependencies, and works great client-side or server-side. Use standalone or as a nodeJS/npm and AMD/requireJS module.

v0.4.1 - Alias accounting.formatNumber() as accounting.format()
v0.4 - Transferred repository to Open Exchange Rates for ongoing maintenance
v0.3.2 - Fixed package.json dependencies (should be empty object)
  • Rewrote library structure similar to underscore.js for use as a nodeJS/npm and AMD module. Use npm install accounting and then var accounting = require("accounting"); in your nodeJS scripts.
  • Also works with requireJS or any AMD module loader.
  • unformat now only attempts to parse the number if it's not already a valid number.
  • acounting.unformat now also aliased as acounting.parse
  • Fixed an IE bug in the defaults method

v0.2.2 - Fixed same issue as \#Num: #24 in formatNumber; switch to Google Closure Compiler for minified version.
v0.2.1 - Fixed issue \#Num: #24 (locally-defined settings object was being modified by formatMoney)
  • Rewrote formatting system for formatMoney and formatColumn for better control of string output
  • Now supports separate formats for negative and zero values (optionally) via accounting.settings.currency.format
  • Internal improvements and helper methods

  • formatMoney recursively formats arrays
  • Added Jasmine test suite (thanks to millermedeiros) and QUnit functionality/speed tests

  • Added configurable settings object for default formatting parameters.
  • Added format parameter to control symbol and value position (default "%s%v", or symbolvalue)
  • Methods consistently accept object as 2nd parameter, matching/overriding the library defaults

  • formatColumn works recursively on nested arrays (e.g. accounting.formatColumn( [[1,12,123,1234], [1234,123,12,1]] ), returns matching array with inner columns lined up)
  • Fix rounding in formatNumber

  • Added toFixed method (accounting.toFixed(value, precision)), which treats floats more like decimals for more accurate currency rounding
  • Minified version preserves semicolons
  • Fixed NaN errors when no value in unformat
