Comment 4 for bug 212768

Confirmed with current SVN builds (0.46+devel r22240, OS X 10.5.8)

When using 'Geometric bounding box' the numeric entry fields of x, y coordinates and bbox height and width in the controls bar of the selector tool don't allow to enter precise values: only after several repeated entries of the same numbers inkscape finally seems to calculate the same values internally and uses the entered numbers. This doesn't happen when using the 'visual bbox' setting.

Reopening this bug and assigning to Diederik (I hope that's ok?) - maybe you could estimate if this is a broader precision issue or could be easily fixed by changing the way the bounding box values are calculated when in 'geometric bbox' mode? This issue makes the geometric bbox mode barely usable for technical drawings IMHO as the workaround to always snap to grid or guides isn't always practical.

related bugs:
Bug #190557 in Inkscape: “resize of object or group by entering a numeric size results in a different size.”
Bug #370137 in Inkscape: “"Geometric bounding box" setting does not affect XYWH edit fields on the Tool Controls bar”

and maybe
Bug #174046 in Inkscape: “Rectangles do not snap accurately to grid”
(the discussion here has a lot of information about the bbox modes and resulting issue (e.g. with snapping or resizing) and really helped me to better understanding the different concepts)
