How do I round up or down a decimal?  For example var myResult = 125.22545  and I wanted to round that up to two decimal points so it is 125.25?
<script>
	var result = document.getElementById('result');	
	var base = parseFloat(baseOne) * parseFloat(myBox1) * parseFloat(myBox5a);
	var myResult = parseFloat(base) + parseFloat(myBox2a) + parseFloat(myBox3a) + parseFloat(myBox4a);
	
	result.innerHTML = myResult;

</script>

var myNum = Number(12.248481545454);

var myRounded = myNum.toFixed(2); // returns 12.25

alert(myRounded)
result.innerHTML = myRounded;

var original=28.453

1) //round "original" to two decimals
var result=Math.round(original*100)/100  //returns 28.45

2) // round "original" to 1 decimal
var result=Math.round(original*10)/10  //returns 28.5

3) //round 8.111111 to 3 decimals
var result=Math.round(8.111111*1000)/1000  //returns 8.111
