Angles are their own object type. An angle is entered by prefixing a number with the angle symbol (∡, AL-RS-6), followed by a number, then finally a suffix that indicates the system (degrees, radians, grads, or DMS [Degrees Minutes Seconds] = DDD.MMSS). For example, the following all indicate an angle of 90.5 degrees:

∡90.5°

∡1.5795.r

∡100.5556g

90.3000d
