Defined in header <functional>
template< class T >
struct divides;
(until C++14)
template< class T = void >
struct divides;
(since C++14)

Function object for performing division. Effectively calls operator/ on two instances of type T.

Contents

[edit] 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
(class template specialization) [edit]
(since C++14)

[edit] Member types

Type Definition
result_type T
first_argument_type T
second_argument_type T

[edit] Member functions

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

(none)

Possible implementation

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