i'm not sure if there is a rounding error but if i generate a PDF from the attached html file, i should get two rows with two cells on each line. instead the second cell in each row overflows and I end up with the cells on separate lines.

if i change the left and right margins to eg 15 or 17mm, then the page renders correctly.

   Test HTML showing (rounding?) error

Yes, rounding error. Changing the width to 49.9% will do the trick.

yes, i'd noticed that too. will this be fixed in a future version? unfortunately i don't have complete control over the style sheets and i don't really want to go and manually override every style that is applied.

It is difficult to fix in the short-term. How about applying a very small negative margin to affected floats, would that be easier to apply uniformly?

yes that would be easier but still not that easy .

does 'not short-term' mean, 'not in 1 week/month' or is it more like 'on the wishlist for v10'?

It would require a fairly fundamental change to Prince internals. This is a change we do plan to make in the future, but it may not be this year.
