Well, in this particular case I would declare pi as a *static* const class member: this way I think its memory should be allocated a single time (for the class definition, being static) insted of being allocated for every class istance (non-static class members) or every time the member function is executed (function scoped vars and consts).. unless their initial value is unknown at compile-time, I think consts should always be defined as static.
