Not able to select the precise value either by clicking on the tick or dragging

[kalagivora]

If I select another value and then try to go back and select '0', I'm not able to select that exact value; it's deviating or giving a nearby value instead.
how do I fix this?

You could use arrow keys left/right to get to the desired spot. (Holding the key makes the value change continuously.)

I accompany the slider with the input text field and buttons to make it all pleasant to use with touch screens (no arrow keys available there obviously).
