--- Comment #14 from Regina Henschel <rb.henschel at t-online.de> ---
The 12mm to 11.99mm problem is not trivial. The internal unit is Twips as
integer value. 1 Twips = 127/7200 mm and 1 mm = 7200/127 Twips.

12.00mm = 680.3149... Twips ≈ 680 Twips
680 Twips = 11.9944... mm ≈ 11.99 mm
And on the other hand, for the next Twips value you get
681 Twips = 12.01208... mm ≈ 12.01 mm

Twips is used, to get a better conversion with point: 1pt = 20 Twips.

I agree, that the input fields in the column size dialog should have more
decimal places, so that it is possible to enter n/8 values.
