You can use the .toFixed function.

If you wish to display only 3 decimal places, use .toFixed(3) to your result.

Example

var num = 15.454182;
alert(num.toFixed(3)); // 15.454

You can use toFixed(3) to do this for you. so your code would be:

document.form.sum.value = ((document.form.sum1.value -0) / (document.form.sum2.value -0)).toFixed(3);

This should work.

function updatesum() {
    var sum = (document.form.sum1.value -0) / (document.form.sum2.value -0);
    document.form.sum.value = sum.toFixed(3);
}
