How to get ordered product count not order qty of product. I want to how many product is there in that order?

I am using this but it showing ordered qty only

 <?php 
        $_order = $this->getOrder(); //call the order
        echo $order_qty = floor($_order->getData('total_qty_ordered')); //get qty of all items rounded to full number (without 3.0000 or so)
        //echo $order_qty;
    ?>
