Need to use decimal type values

[irshadsparky]

He developers, Thankyou for this library i am facing problem with useing float or double type value in range selecter .Return values are always in int

[bmx666]

Example, for using range as float/double values:

• Require range from 0.1 to 0.7 with step 0.2
• Set min 1, max 7, step 2

  private static final double SCALE_FACTOR = 10.0;
  ...
  multiSlider.setStep(2);
  multiSlider.setMin(1, true, true);
  multiSlider.setMax(7, true, true);
  multiSlider.setOnThumbValueChangeListener(new MultiSlider.OnThumbValueChangeListener() {
      @Override
      public void onValueChanged(MultiSlider multiSlider, MultiSlider.Thumb thumb, int thumbIndex, int value) {
          final double value_d = value / SCALE_FACTOR;
          doSmth(value_d);
      }
  });
