I have created a javascript priceupdater on a site and when the price ends in 0 the 0 is cut off. I've been looking for a function to keep the 0 added?

EG price is £12.60

and my dynamic price updater shows £12.6 I need it to change to £12.60

if (price.lastIndexOf(".") == 2) {
 	price += "0" ;
}

I couldn't get the code below to work. However....

if (price.lastIndexOf(".") == 2) {
 	price += "0" ;
}

I've found an inbuilt function

price.toFixed(2);

This is useful for floating points. This method will keep your number to 2 digits after the point.

Most programming languages support something like "printf" which gives you formatted printing. I looked around and found something kinda neat. This script (source at the bottom) will allow you to use standard sprintf function calls.

Hope it helps
