Range Slider unable to set StepSize property

[gfxx]

on my ui.qml file I insert a rengeSlider and in designer I set StepSize to 1,00 (but 10,00 is the same) to try to have rangeslider.first.value and rangeslider.second.value as integer only value (so 1,00 - 2,00 - 3,00 - 4,00 and so on).
But the value returned is only double with decimal part (0,789185 - 1,981625 - 2,65816 and so on).

Where are my error?

Update ... after these code in myFunction:

            property int  integerValue: 0
            property double doubleValue: 0
            property int  integerValueSlid1: 0
            property double doubleValueSlid1: 0
            property int  integerValueSlid2: 0
            property double doubleValueSlid2: 0


            function changeRangeValue(){
                doubleValueSlid1 = 0
                integerValueSlid1 = 0
                doubleValueSlid2 = 0
                integerValueSlid2 = 0
                doubleValueSlid1 = rangeSliderNum.first.value
                integerValueSlid1 = doubleValueSlid1
                doubleValueSlid2 = rangeSliderNum.second.value
                integerValueSlid2 = doubleValueSlid2
                //console.log((integerValueSlid1))
                teTempoMinSlider.text = integerValueSlid1
                teTempoMaxSlider.text = integerValueSlid2 - integerValueSlid1

the range slider work ok!!
I write this just because it is added to the search for the forum ... can serve someone.
