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

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 (until C++11)
std::binary_function<T, T, T>.

Member functions¶

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