How to add a trailing zero to a price?


I have a script which returns a price for a product. However, the price may or may not include trailing zeros, so sometimes I might have 258.22 and other times I might have 258.2. In the latter case, I need to add the trailing zero. How would I go about doing this?


Solution

  • You can use javascript's toFixed method (source), you don't need jQuery. Example:

    var number = 258.2;    
    var rounded = number.toFixed(2); // rounded = 258.20
