Sorry, I think you've got the wrong end of the stick. What I mean is if the
difference between the sizes you changed in 'em's is less than 1 pixel then
the browser can't show it (for obvious reasons).
So taking the following example:
----------------------------
/* === old === */
p {
    font-size: 1em;
}

/* === new === */
p {
    font-size: 0.99em;
}
----------------------------
If the size of the old style size translated into pixels was 12px (for
example), then if the new style's  translated size were 11.75px, it can't
show points of a pixel as your monitor can't do it.

Hope that makes more sense. I don't mean you yourself should change the
sizes using a calculator, what I mean is the browser needs to work out how
many pixels a font is when it displays it. You yourself work with the 'em's
because they're relative.
