My problem with decimal speeds

#
In a game I'm making. I want my character to move down in a decimal speed, but it just turns in a big circle and doesn't fall like it should. 
public class Bag extends SmoothMover
{
    private double BagSpeed = 0.5;
    /**
     * Act - do whatever the Bag wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        move(BagSpeed);
        turn(3);
        
        if (Greenfoot.isKeyDown("right"))
        {
            setLocation(getX()+3, getY());
            

        }
        if (Greenfoot.isKeyDown("left"))
        {

            setLocation(getX()-3, getY());

            

        }
    }    
}

It's supposed to rotate a bit, but not like it has been

You probably need to use getExactX and getExactY instead of getX and getY in your setLocation lines. As is, you are killing the precision by negating the fractional part of the coordinates.
