How to set decimal step in slider

I am using dhtmlx 4 now,and want to set step to decimal value,but it seems that it can not work correctly.

mySlider.setStep(0.5);
mySlider.setMin(1);
mySlider.setMax(10);

if it is set to Integer,it can work correctly

mySlider.setStep(1);

how to set the step to decimal,such as 0.5 or 0.8 ?
