public class JRationalSlider
extends JSlider

A slider that converts its integer value with a rational function.

   x  = a+b/x_int^n
   

Where the two constants are defined through the minimum and maximum values supplied on construct. For zero power, i.e. n = 0, the rational in x is replaced with the logarithm of x_int. (xs-xe)=b(1/xmin^n-1/xmax^n)->b
