JSlider using double values instead of INT

Question

I need to create a slider that uses double values instead of ints...
the default constructor is JSlider temp = new JSlider(JSlider.HORIZONTAL, int, int, int)....but i need to use
JSlider temp = new JSlider(JSlider.HORIZONTAL, double,double,double)
I want my slider to go from like 1.0 to 10.0 ....any ideas?
thanks
