But it isn't just a number. It's an angle. That conveys meaning. Angles have multiple representations for example. In Radians and Degrees, and who knows what else. Hence the Math::Angle class has a method "degrees" and a method "radians". Converting a degree value to radians: 
say 75°.radians; # yes the ° is a custom constructor. alternatively Ma
+th::Angle.new(degrees=>75).radians;

Also it behaves like a number where it makes sense. 
ok 75° < Math::Angle.new(radians => pi);

Or even 
ok 75° + 75° == 150°;
