I’ve just released a new build of slikcalc – javascript calculator library that includes a few small bug fixes, and some shortcuts to the API. The new API for creating calculators looks as follows: as opposed to: Its a small change, but I think is easier to use. Of course the old way will still [...]

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.

I’ve put together a small javascript library that greatly simplifies creating dynamic javascript calculators. It works great for just about anything, ranging from calculating columns of values, to a complex custom formula. You can even write your own calculators and plug them into the framework with little effort.
