Like the title is saying, it should be nice to have a way to round of the coordinate system to a specific number of digits. As mostly there is no use to have coordinate numbers with more then 0 digits behind the zero, make it configurable. Say for example that i'm making a mechanical design, a resolution of 0.01 or 0.001 mm is more then enough, non need in having smaler numbers.
Still seeing faults caused by vertices that are off by a billionth of a mm which causes solids not to add/subtract correctly. Only zooming in on vertices up to the max will show that two vertices are not actually having the same coordinates.
