Standard C++ Library Copyright 1996, Rogue Wave Software, Inc. NAME divides - Returns the result of dividing its first argument by its second. SYNOPSIS #include <functional> template <class T> struct divides; DESCRIPTION divides is a binary function object. Its operator() returns the result of dividing x by y. You can pass a divides object to any algorithm that requires a binary function. For example, the transform algorithm applies a binary operation to corresponding values in two collections and stores the result. divides would be used in that algorithm in the following manner: vector<int> vec1; vector<int> vec2; vector<int> vecResult; transform(vec1.begin(), vec1.end(), vec2.begin(), vecResult.begin(), divides<int>()); After this call to transform, vecResult[n] will contain vec1[n] divided by vec2[n]. INTERFACE template <class T> struct divides : binary_function<T, T, T> { typedef typename binary_function<T, T, T>::second_argument_type second_argument_type; typedef typename binary_function<T, T, T>::first_argument_type first_argument_type; typedef typename binary_function<T, T, T>::result_type result_type; T operator() (const T&, const T&) const; }; binary_function, function objects STANDARDS CONFORMANCE ANSI X3J16/ISO WG21 Joint C++ Committee
