JavaScript: formatting number with exactly two decimals

Now that I have got a bit of script to add values in to a div with a total in it, I then try to divide the values by 100 to give me a decimal number (to make it look like currency).

After this the script works and gives me a nice decimal float, sometimes though a large recurring number comes after, I want to limit this to two decimals using the script i already have so was wondering if someone could implement something into my current script.

$(document).ready(function() {   $('.add').click(function() {      $('#total').text(parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100);   }); })

You need to use the .toFixed() method

It takes as a parameter the number of digits to show after the decimal point.

$(document).ready(function() {   $('.add').click(function() {      var value = parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100      $('#total').text( value.toFixed(2) );   }); })
