Ruby-like Question: Make this function shorter (ActionScript 3)

Question

I just wrote this incredibly verbose code to turn numbers like 2 into 02. Can you make this function shorter, please (maintaning the functionality)?

Answer 1

The as3corelib package put out by adobe has a nice little NumberFormatter class that uses a series of STATIC classes. In this case you could use the addLeadingZero function.

//The following method is from the NumberFormatter class of the as3corelib package by Adobe.
public static function addLeadingZero(n:Number):String
{
var out:String = String(n);

if(n < 10 && n > -1)
{
    out = "0" + out;
}

return out;
}

I included the function just to show it's simplicity, but I would use the package instead of yoinking the function because it provides many other useful features like StringUtils, encryption methods like MD5, blowfish, etc.

You can download the package here For newer users you must provide a classpath to where this package lives. It is also smart to import the classes instead of using their fully qualified class names.
