Currently I am assigning values with decimals which come from a CSS pre-processor or from calculations from JavaScript. On one hand the value is more precise without modifying it and there is one less operation to be done, but on the other hand after the first digit the following are unnoticeable and I am not sure if these affect the browser performance in some way.
div { width: 33.333333333333%; }
vs
div { width: 33.33%; }
$('div').width(100 / 3); // 33.3333...
vs
$('div').width(Math.round(100 / 3 * 100) / 100); // 33.33
Does it affect the browser performance to have several decimal values in the CSS?
This is a very basic example.
