For some mental fun, try these values for the angle and see what observations you can make about the results:

76.34541

126.869896

137.50777

However, I find it a bit bothersome that the input field doesn't properly accept floats, and the floats get rounded unnecessarily. Please don't do that, or have an option to customize it.

Also, you miss the more obscure trigonometry values:

Namely, to quote from the above page:

Versine, Vercosine, Coversine, Covercosine, Exsecant, Excosecant, Haversince, Havercosine, Hacoversine, Hacovercosine

You might also wish to expand this by adding, in addition to the already shown degrees & radians, the following angle measures:

* Gradian * Turns * Arcminutes/Arcseconds

They're golden angles! https://link.springer.com/content/pdf/10.1007%2Fs00004-015-0...

Well the last one is. The significance of the other two angles, in OPs diagram, is unclear to me.

You're right! I've added a new section named 'general options' and 'rounding numbers' option under it to you can disable rounding. I hope it helps, if not please tell.

And thanks about other great suggestions, those are really interesting. I'll check and try to bring them into party!
