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 .

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.

(C++14)
function object implementing x / y deducing parameter and return types
(class template specialization)
(since C++14)

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 std:: binary_function < T, T, T > .

(until C++11)

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 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;
}
