How do you return more than one value

1

in a function

function randomness(){

var randX:Number = Math.random();
var randY:Number = Math.random();
var max1:Number = 650;
var max2:Number = 450;

var Xoutput:Number = Math.round(randX * max1);
var Youtput:Number = Math.round(randY * max2);


return Xoutput;
    return Youtput;

}

only gives me one value.
