I had a question from a user asking whether it was possible to round the Average that is displayed on SharePoint views to 2.d.p.
Out of the box this is not possible but with a little bit of JQuery we can find the average and round it to the required d.p.
var value = $(this).html();
var num = value.replace('Average = ','');
var result = Math.round(num*Math.pow(10,2))/Math.pow(10,2);
$(this).replaceWith('<b>Average = '+result+'</b>');
