NoUISlider: Format Data as Number

[johannesschobel]

Dear @andrewtelnov and @dmitrykurmanov ,

in #165 we discussed, if the display value in the tooltip could be manipulated in order to not show decimal points. However, in this context, i noticed, that the actual value returned by the NoUiSlider is a string "12.34" and not a Number.

I think, it would be better to actually cast the return value to a Number, like so:

slider.on("change", function() {
  question.value = Number(slider.get());
});

in this file https://github.com/surveyjs/widgets/blob/master/src/nouislider.js#L103-L105

Beside the type cast, this will not be a breaking change. What do you think?
All the best
