[edit]

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 callsoperator/ on two instances of typeT.

[edit]Specializations

The standard library provides a specialization ofstd::divides whenT is not specified, which leaves the parameter types and return type to be deduced.

divides<void>

(C++14)

function object implementingx/ y deducing parameter and return types
(class template specialization)[edit]

(since C++14)

[edit]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 inheritingstd::binary_function<T, T, T>.

(until C++11)

[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;		(constexpr since C++14)

Returns the result of division oflhs byrhs.

Parameters

lhs, rhs

values to divide one by other

Return value

The result oflhs/ rhs.

[edit]Exceptions

May throw implementation-defined exceptions.

Possible implementation

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