So it's very likely the result will have many more changed digits when you run it in DEG mode, and the error doens't come only from the additional conversions, but from the fact that you are using much smaller angles.

Yes, that could be the source. Even this "test" seems to me to be a "symmetrical transformation", the symmetry will not compensate for errors coming from the harder cases inside..

Thanks!
