std::divides(3)

NAME
std::divides - std::divides

Synopsis
   Defined in header <functional>
   template< class T > (until C++14)
   struct divides;
   template< class T = void > (since C++14)
   struct divides;
   Function object for performing division. Effectively calls operator/ on two
   instances of type T.

Specializations
   The standard library provides a specialization of std::divides when T
   is not specified, which leaves the parameter types and return type to
   be deduced.
                        (since C++14)
   divides<void> function object implementing x / y deducing parameter
   (C++14) and return types
                 (class template specialization)

Member types
   Type Definition
   result_type (deprecated in C++17)(removed in C++20) T
   first_argument_type (deprecated in C++17)(removed in C++20) T
   second_argument_type (deprecated in C++17)(removed in C++20) T
   These member types are obtained via publicly inheriting (until C++11)
   std::binary_function<T, T, T>.

Member functions
              returns the result of the division of the first argument by the second
   operator() argument
              (public member function) std::divides::operator()
   T operator()( const T& lhs, const T& rhs ) const; (until C++14)
   constexpr T operator()( const T& lhs, const T& rhs ) const; (since C++14)
   Returns the result of division of lhs by rhs.

Parameters
   lhs, rhs - values to divide one by other

Return value
   The result of lhs / rhs.

Exceptions
   May throw implementation-defined exceptions.

Possible implementation
   constexpr T operator()(const T& lhs, const T& rhs) const
   {
       return lhs / rhs;
   }
