rounding numbers

**napoleonv** · 11-16-2006 12:52 PM

Hello everyone,

I have the following code:

<html>
<body>

<script type="text/javascript">
var result=Math.round(10.10123*100)/100 //returns 10.1
alert(result)
</script>

</body>
</html>

This script alerts 10.1 and not 10.10

Is there anyway to make it so that it rounds to two decimal places all the time?

TYI

var result=(Math.round(10.10123*100)/100).toFixed(2)

That can be shortened to Number.toFixed (2)

Charles means:

Code:

var result=(10.10123).toFixed(2)

The toFixed method will already round to the fixed digit after the decimal place and there is no need to do it twice. Also it should be noted that the toFixed method was added in Javascript 1.5 and older browsers like Safari and IE prior to 5.5 don't support it. Therefore you may want to define it for older browsers, but first test for it.
