Brackets missing in Example-1.5

I believe it should have been 
return { x: (x - bbox.left) \* (canvas.width  / bbox.width),
            y: (y - bbox.top)  \* (canvas.height / bbox.height)
          };
instead of(missing brackets)
   return { x: x - bbox.left \* (canvas.width / bbox.width),
            y: y - bbox.top \* (canvas.height / bbox.height)
          };

in windowToCanvas method of example.js in example-1.5.
