29 /// @brief Generic implmentation of the AIFMath implementation using AIFTuple
30 ///
31 /// The GA_AIFMath class provides a pure virtual interface requiring developers
32 /// to implement all specializations of the arithmetic operations. However,
33 /// there are a lot of methods to implement. If your attribute provides an
34 /// AIFTuple numeric interface, AIFStdMath will use this interface to perform
35 /// many operations. If you sub-class from AIFStdMath instead of AIFMath you
36 /// can still specialize bottleneck operations while providing a complete
37 /// interface.
38 ///
39 /// However, <b>be warned</b>, if the AIFMath interface changes, you may
40 /// end up missing opportunities for specialization.
