Dear Deane Yang,

In return a took a look at your example and would suggest the following 
changes:

    // Addition and subtraction
    this_type& operator+=(const floating_type term);
    this_type& operator+=(const this_type& term);
    this_type& operator-=(const floating_type term);
    this_type& operator-=(const this_type& term);

similar changes for  *=,/=. Or is there a reason for const return type ?

std::valarray<FloatingType> f;
to simplify the implementation of some operations.
Note, you should use  f[Order+1] .
