    A question about operator overloading

    I have a 3D vector class. I have overloaded operator *= such that it can take a scaler value on the right hand side. That is working fine.

    Now I have a second loaded operator* which takes a Vector3D arg AND a scaler arg.

    So, it would work thus:

    Vector3D scaledVec = oldVec * 3.0;

    My question is, how would I make the operation commutative such that the following would also be valid:

    Vector 3D scaledVec = 3.0 * oldVec;

    Must I overload the function?

    Create a global overloaded version of the function, something like

    operator* ( double , Vector3D& )

    I'm in the middle of studying for a psychology test, so if I'm talking rubbish, ignore me.
