Interface: NavAngleUnit

A navigation angle unit, which is a measure of angular degrees relative to either true or magnetic north.

Unlike most other unit types, each instance of navigation angle unit contains state specific to that instance, namely the magnetic variation used to convert between true and magnetic bearing.

Conversions use the magnetic variation of the NavAngleUnit instance whose conversion method is called; this also means that when calling NumberUnit.asUnit(), the magnetic variation of the unit of the NumberUnit whose asUnit() method was called will be used.
