Comment 6 for bug 168002

> try increasing the precision as suggested above and see if this is still reproducible?

Inkscape 0.47+devel r9542 on OS X 10.5.8
- rectangle with no fill, stroke-width 10px
- grid spacing 1px, snap to visible lines, zoom 100%
- tested with both visual and geometric bbox mode
- tested with both snap bbox corners or snap nodes to grid
- verified by watching live updates in the XML Editor

Precision 8 (default): reproduced - sometimes the stroke width gets modified slightly, most of the times the x/y and/or height/width parameters of the rectangle have rounding errors, not displayed in the select controls bar fields.

Precision 16: still reproducible but not consistently: randomly and rarely seen rounding errors of the stroke width, mostly when dragging the left bounding box edge (de-/increasing the width of the rectangle). The x, y, width and height parameters show no rounding errors when precision is raised to 16.

Possibly related to bug #190557 in Inkscape: “resize of object or group by entering a numeric size results in a different size.”?
(still reproducible in current 0.47+devel builds, shows varying rounding errors of shape position and dimension however rarely affects stroke-width attribute)
