Single number coordinates display

Hi, I'm displaying the camera World coordinates using the below code which works well but it displays a string of decimals. How can I reduce the string to single Numbers, thanks?

function OnGUI () { GUI.Label (Rect (10,10,500,100), " X= " + transform.position.x + " Y= " + transform.position.y + " Z= " + transform.position.z); }

Heres What I would do

private var xPosition : int;
private var yPosition : int;
private var zPosition : int;

function Update () {
    xPosition = transform.position.x;
    yPosition = transform.position.y;
    zPosition = transform.position.z;
}

function OnGUI () { 
    GUI.Label (Rect (10,30,500,100), " X= " + xPosition + " Y= " + yPosition + " Z= " + zPosition);
}
