How about this:

var number = Math.round(14.85 * 10) / 10;

Here is the solution that produces the exact result what you need:

function roundFloat(n) {
    return (Math.round(n * 10) / 10).toFixed(2);
}

roundFloat(14.84);  // "14.80"
roundFloat(14.85);  // "14.90"

var newNumber = (Math.round(oldNumber*10)/10).toFixed(2);
