public interface MathFunctionsAbs<T>
extends Serializable

Interface to force a limited number of functions of Math to be implemented for absolute values. Note: a lot of standard Math functions are not implemented, as they don't make sense with the units. E.g., a cubic root of a Volume should give a Length, and not another volume... Trigoniometric functions should not give back the same unit either. The abs() function is not included here, as abs() only makes sense for relative vales. What is the absolute value of 14 January 2016? Therefore the functions that the interface forces to implement is rather limited, and certainly not the entire range of java.lang.Math functions.
