std::divides

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 argument 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;
 (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;
}
