can someone explain this function for two decimal places

[robGtech]

Hello I found this function here yesterday and while it works great for values of only 1 decimal place, when I get a value with no decimal place it doesn't work. Can some one help me modify this.

I'm using Math.round and if I get 65, I need it to display 65.00

function numberFormat(str)
{
	str = str.toString();
    if(str.indexOf(".") == -1)
    {
        return str;
    }  
    splitString = str.split(".");
    
    var newSplitString = splitString[1];
    
    for(i=0; i < (2 - splitString[1].length); i++)
    {
        newSplitString = newSplitString + "0";
    }
    
    return (splitString[0] + "." + newSplitString);
}

Thanx

evidently someone was trying to reinvent the wheel.

take a look at this:

<script type="text/javascript"><!--

var v1 = 1234.567890;
var v2 = 1234.56;
var v3 = 1234.5;
var v4 = 1234;
var v5 = .12345;

document.writeln( v1 + " becomes " + v1.toFixed( 2 ) + "<br />" );
document.writeln( v2 + " becomes " + v2.toFixed( 2 ) + "<br />" );
document.writeln( v3 + " becomes " + v3.toFixed( 2 ) + "<br />" );
document.writeln( v4 + " becomes " + v4.toFixed( 2 ) + "<br />" );
document.writeln( v5 + " becomes " + v5.toFixed( 2 ) + "<br />" );

//--></script>

in other words, that function you have is not necessary.

re-inventing the wheel indeed. What you wrote there works perfect.

Thank you
