Round to at most 2 decimal places (only if necessary)

I have three text inputs, two where the user enters figures and one which shows the result of the two text boxes multiplied together.
function calculate() {
var myBox1 = document.getElementById('box1').value;
var myBox2 = document.getElementById('box2').value;
var result = document.getElementById('result');
var myResult = myBox1 * myBox2;
document.getElementById('result').value = myResult;
}
This works fine, however is there a way to show the multiplied number/field to 2 decimal places?
Eg, rather than showing 46.800000000000004 it would show 46.9?
