How to determine if mouse cursor is over GUIBox?

I would like to know how it could be done with lesser cost. Sure I can check if coordinates of cursor are in the specified area (compare x and y) but it will be at least 8 logical comparisons in my case and not efficient at all. Any ideas?

Use Rect.Contains

 function OnGUI() {

 var BoxRect = new Rect(100,100,100,200);

 GUI.Box(BoxRect,"My GUI Box");

 if (BoxRect.Contains(Event.current.mousePosition)) 
 // Whatever you want
	 print("Mouse inside");

Use Rect.Contains.

I suppose it’s done so the eight tests are not done if it’s unnecessary.
