ActionScript: Random number function

I saw that one of the top results for "actionscript random number" in a Google search is incorrect, so I figured it would be a good idea to post another proper one.

Here's the ActionScript 3 version:

function randNum( low:int, high:int ):int
{
 return Math.round( Math.random() * (high - low) ) + low;
}

And here's the ActionScript 2 version:

function randNum( low:Number, high:Number ):Number
{
 return Math.round( Math.random() * (high - low) ) + low;
}
