NoUISlider Tooltip only show integers

I want that the tooltip on my slider only shows integers like "130" and not "130.00".
I just dont know where i could start.

Here is my code:

$( document ).ready(function() {
var groesseslider = document.getElementById('slider-tooltip');

noUiSlider.create(groesseslider, {
start: [ 145 ],
step: 1,
range: {
'min': 100,
'max': 250
}
});
});
$( document ).ready(function() {
var groesseslider = document.getElementById('slider-tooltip');
var tipHandles = groesseslider.getElementsByClassName('noUi-handle'),
tooltips = [];

// Add divs to the slider handles.
for ( var i = 0; i < tipHandles.length; i++ ){
tooltips[i] = document.createElement('div');
tipHandles[i].appendChild(tooltips[i]);
}

// When the slider changes, write the value to the tooltips.
groesseslider.noUiSlider.on('update', function( values, handle ){
tooltips[handle].innerHTML = values[handle];
});
});

Answer

You can either try using the unencoded value like described in noUISlider's documentation about events and their binding

slider.noUiSlider.on("update", function(values, handle, unencoded ) {
    // values: Current slider values;
    // handle: Handle that caused the event;
    // unencoded: Slider values without formatting;
});

or another possibility would be using the format option on slider creation (but haven't tried it myself yet):

noUiSlider.create(slider, {
    start: [ 20000 ],
    ...
    format: wNumb({
        decimals: 0, // default is 2
        thousand: '.', // thousand delimiter
        postfix: ' (US $)', // gets appended after the number
    })
});

The drawback is you have to download the wNumb-Library separately from here: http://refreshless.com/wnumb/.


Another way without wNumb

After having another look at the examples from noUISlider, I found this way for manually formatting (at the bottom of the page):

var sliderFormat = document.getElementById('slider-format');

noUiSlider.create(sliderFormat, {
    start: [ 20 ],
    ...

    format: {
      to: function ( value ) {
        return value + ',-';
      },
      from: function ( value ) {
        return value.replace(',-', '');
      }
    }
});
