std::divides: std::divides

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.

              function object implementing x / y deducing argument and return types (since C++14)
divides<void> (class template specialization)

Member types

Type Definition (until C++20)
result_type(deprecated in C++17) T
first_argument_type(deprecated in C++17) T
second_argument_type(deprecated in C++17) T

Member functions

           returns the result of the division of the first argument by the second argument
operator() (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

(none)

Possible implementation

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