css('border-top-width' ) bringing back 5 decimals.

css('border-top-width' ) bringing back 5 decimals.

I have some code that creates a box:




The baseCell$ on line 9700 that it starts from is a clone of a box template defined a few lines earlier:
  1. baseCell$  = $('#boxTemplate').clone(); 
The problem is that even though the value I'm setting for border width is 1px (see line 9735) the value I read back with css('border-top-width' on line 9736 is 1.11111px. 

Here's the actual console.log output from lines 9735 and 9736:



Does anyone have an idea what might be going on here?

Thanks
Steve
