Sounds great. I’m working on the tests now, but this whole thing is just for my [idea](https://discourse.julialang.org/t/should-there-be-a-native-angle-type/4611) with the `Angle` type. I defined all the functions needed for the conversions and the trigonometry, but now “all” I need is for this Angle type to behave like a `Number` (or `AbstractFloat`) in every other situation…
