Method scrollTop() - works wrong in Internet Explorer

Method scrollTop() - works wrong in Internet Explorer

Hello Everyone,

      I am facing an issue with the method "scrollTop".

I have 2 div tags what are the same sizes of height, width and the vertical scroll bar. when I scroll the first div, I want that the second div is also scrolled in the same position with the first div . I implemented this by the way:

$('div_id2').scrollTop($('div_id1').scrollTop());

It works fine in Firefox and Chrome, but I got a small position deviation between 2 vertical scroll bars of the div tags in IE .
when I try to log the values:
    console.log('div_id1:' + $('div_id1').scrollTop());
    console.log('div_id2:' + $('div_id2').scrollTop());

=> result in Chrome, Firefox: div_id1:44.545454446934474
                                               div_id2:44.545454446934474

 => result in Internet Explorer:  div_id1:45
                                                div_id2:45

I am not sure that the difference causes getting a small position deviation between 2 vertical scroll bars, or not?
Please help me how to overcome this issue!

Many thanks,
