[SOLVED] sprintf in javascript?

[therealwesfoster]

I'm wanting to restrice how long a dynamic money amount can be.

 

For instance, I want $2.4200000000000004 to be $2.42. I know that you can do this in php using the sprintf function, but how would you go about doing this in javascript?

 

Thanks

<script language="javascript">

var original=2.4200000000000004;
var change=Math.round(original*100)/100;

alert("$"+change+""); // you can take this our; just for demo purposes

</script>

Much appreciated. Worked like a charm. So simple.
