rounding to 2 decimal places

rounding to 2 decimal places

i have a little script that counts the total of a column in a table

  1. $(function () {
    var TotalCoreProd = 0;
    $("[id*=col01]").each(function () {
    TotalCoreProd = TotalCoreProd + parseFloat($(this).html());
    });
    $("[id*=TotalCoreProd]").html(TotalCoreProd.toString());
    });
problem is, it's outputing the value with about 20 decimal places.
i need to round this to 2 decimal places.
i believe ".tofixed(2)" should be used, but no matter where i try and place it, it ends up causing the code the fail completely.
