Interface DimensionlessFunctions<U extends Unit<U>,T extends Value<U,T>>

Type Parameters:
U - the unit of the type
T - the type of the (dimensionless) value that the functions operate on
All Known Implementing Classes:

public interface DimensionlessFunctions<U extends Unit<U>,T extends Value<U,T>>
Interface to force most functions of Math, which have not yet been implemented by MathFunctionsRel, to be implemented, with the exception of toRadians() and toDegrees() -- these functions are available for angles.
