A new version of Slikcalc (1.0) was released. This release simplified some code, mainly the slikcalc.formatCurrency() method. There was also a bug where a calculator could be initialized more than once depending on timing that was fixed. As always, feel free to leave feedback on the library. Enjoy. Download Slikcalc 1.0

While working on Slikcalc, I was trying to find the easiest way to format a number for currency. I had found some implementations that were pretty complex, using regex and absolute values, and thought there had to be a simpler way. This is what I came up with and so it works great in all the browsers I’ve tested (IE 6/7, Firefox 2 (windows & mac), Opera 9 (windows and mac).

function formatCurrency(num) {
  num = isNaN(num) || num === '' ? 0.00 : num;
  return parseFloat(num).toFixed(2);
}

Just thought I’d share for anyone working with something similar.
