Ok, so I’ve read quite a bit on formatting and I’m good to go on currency, numbers with commas, etc.

I’ve been trying for awhile to format a percent number and I’ve gotten relatively close to where I want to be:

```auto

public static function percent(n:Number):String {
            
            //Converts the argument to a string with the percentage symbol
            var output:String = Math.ceil(n*100).toString() + "%";

            //Returns the reformatted percentage
            return output;
        }

```

The problem here is that I need to be able to set precision and I keep messing it up when I try to write something… here’s an example:

**Number:** 0.203948278358292  
**Result with the above code:** 20%  
**Desired Result:** 20.39%

Can anyone help me with this?🔗
