This is probably a silly question - and not an important one - but I have noticed that sometimes when using exact centimetre values in walls and furniture in SH3D, the values are often off by a minute fraction in Home.xml (and exported .obj). E.g. a wall 17,5cm down becomes yStart='-17.499971' in Home.xml.

Not that it matters much, but I wonder whether there is a reason I do not understand.
