I'm sure the answer to this is out there somewhere, but I'm having trouble finding it. (wearing flame-retardant clothes...) I want to use boost::operators::field_operators to generate all the mathematical operators to allow Vector/scalar arithmetic. Everything works fine except for dividing scalars by vectors. Class Vector looks like this: class Vector : public std::vector<double>, boost::field_operators > { // required operator+=, -=, *=, /= defined here. }; Now if I write: double x(3.0); Vector v(5), w; v[0] = 1; v[1] = 2; v[2] = 3; v[3] = 4; v[4]=5; w = 3+v; // works fine w = v+3; // works fine ... // subtract and multiply work on both sides w = v/x; // works fine w = x/v; // fails... I think the failure happens because of the way operator/ defined for mixed types something like this: T operator/(U u,T t) { T ans(u); ans/=t; return ans; } which is not what I need. Is there a way I can change the way operator/(double,Vector) works in this one case, but keep the really convenient definitions generated by field_operators otherwise?
