Magento Price Formatting - 2 or 3 decimal places <p>I have a requirement to set prices on certain items to 3 decimal places. I have achieved this by changing the 'precision' variable to 3, however this now means that every price on the site is displayed to 3 decimal places (ie: an empty shopping cart shows as £0.000). I want to only show the 3rd decimal place if it's required but I'm not sure where to find this in the code base. Can anyone point me in the right direction please?</p>
