This class is specialized for all 16 combinations of standard types (that is, real and complex types in each of two precisions) and has typedefs "Type" which is the appropriate "narrowed" type for use when R1 & R2 appear in an operation together where the result must be of the narrower precision, and "Precision" which is the expected precision of the result (float, double).

This class is specialized for all 16 combinations of standard types (that is, real and complex types in each of two precisions) and has typedefs "Type" which is the appropriate "narrowed" type for use when R1 & R2 appear in an operation together where the result must be of the narrower precision, and "Precision" which is the expected precision of the result (float, double).
For example, if R1=complex< double > and R2=float, Narrowest<R1,R2>::Type is complex< float > and Narrowest<R1,R2>::Precision is float.
