While working on my addon, I found that object rotation may greatly increase float error. Closer it to 180 degrees - more error it cause. It make some calculations in my addon work wrong so I started to code some adjustment measures for increasing values check threshold.
Interesting thing I found is that if object rotated to 180 in viewport (R+Z+180), it cause bigger float error than if object was rotated to same 180 deegres by typing value to transforms panel… always. What you think about it guys? Does it deserve to be bug reported or it lay in some “nature of” modal transform operator we perform in viewport (so it cause bigger error)? Or maybe it better to go first or some devtalks with this issue?
