template<class T>
valarray<bool> operator>=(const T& x, const valarray<T>& y);The first template operator returns an object of class valarray<bool>, each of whose elements I is x[I] >= y[I]. The second template operator stores in element I x[I] >= y. The third template operator stores in element I x >= y[I].
