triplex<T> operator+(const triplex<T>& o) const; triplex<T> operator-(const triplex<T>& o) const; triplex<T> operator*(const triplex<T>& o) const; triplex<T> operator/(const triplex<T>& o) const; triplex<T> operator-() const; triplex<T>& operator+=(const triplex<T>& o); triplex<T>& operator-=(const triplex<T>& o); triplex<T>& operator*=(const triplex<T>& o); triplex<T>& operator/=(const triplex<T>& o);
These operators execute the respective equivalent C++ standard arithmetic operation on the triplex<T>.
