JS 文本框加法运算保留2位小数

用以下代码计算小数运算，会出现多位小数，如何精准保存2位小数！本人小白，请大侠提供完整代码
<SCRIPT LANGUAGE="JavaScript">
window.onload = function()
var inputs = document.getElementsByTagName("input");
for(i=0;i<inputs.length;i++)
inputs[i].onblur = function()
var add1 = document.getElementById("add1").value;
var add2 = document.getElementById("add2").value;
var add3 = document.getElementById("add3").value;
document.getElementById("sum").value = add1*1 + add2*1+ add3*1;



</SCRIPT>
<input id="add1" type="text"/> +
<input id="add2" type="text"/> =
<input id="add3" type="text"/> =
<input id="sum" type="text"/>

参考技术A document.getElementById("sum").value = (add1*1 + add2*1+ add3*1).toFixed(2)
