I would like to know in AS3.0, how do i

pad 0 in front of the integer upon converting to string  
eg:

1 --\> 0001  
11 --\> 0011

so that i ll have consistent number of digits…

</div>

```auto

function fullLength(val:String, targLength:int = 4):String
{
	var retS:String = val;
	
	if (val.length < targLength)
	{
		for (var z:int = 0; z < targLength - val.length; z++)
		{
			retS = "0" + retS;
		}
	}
	
	return retS;
}

trace(fullLength("1")); //returns 0001
trace(fullLength("621")); //returns 0621

```

That should do the trick. :thumb:

_ **edit:** _ I added it as a parameter that defaults to 4. If you want a different length, change the default, or pass it like this:

```auto

trace(fullLength(myString, targetLength));

```

i thought there should be a built in function for this …  
but thanks anyway. 🙂

You could also do:

```auto
function fullLength(val:String, targLength:int = 4):String {
	return val.length < targLength ? new Array(targLength - val.length + 1).join("0") + val : val;
}

trace(fullLength("1")); //returns 0001
trace(fullLength("621")); //returns 0621 

```

Or just have it untyped until you pad the 0 and then cast it.
