Describe the bug

I'd like to state this is a both bug, and a small suggestion as to how I think it can be solved.

Whether it be rotation, Pose, or any others that has a angle setting page, you cannot line up symmetrically.
for easier understanding, I have a screenshot, and to explain it, let's say you want to set up the NPC's both left and right arm into 95 and -95. either one side, whether it be left or right, usually ends up in 93, about 2 degrees short. It's barely noticeable, but it is a little annoying.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'NPC's Pose setting'
2. Click on 'Left and Right Arm's Angle, and try to set both into either -95 and 95 like I mentioned.'
3. See error

Expected behavior
Both Arms lining up in a perfect number I intended, not having 2 angles short.

Screenshots
here's a little screenshot to help.

Thanks for the report. I already working on a fix for this by allowing using the keyboard to increase / decrease the numbers in 0.5 steps or so, which should help to get the exact numbers easily.

You can adjust most slides with the mouse wheel and the cursor keys since the latest beta.
