Re: 3 decimals is not a lot of precision for rotation matrices

No. Because you can do a scale and rotate at once.

And even if your part is a rotation matrix, simply scaling it will make it no longer a rotation matrix.

There is a safe way to do it, but it's complicated. When I get enough spare time I'll write a bit of a document on safely determining the 3D angle of a rotation matrix, and fixing it. It is not, however, a simple procedure!
