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

std:: divides < void > is a specialization of std::divides with parameter and return type deduced.

Member types

Type Definition
is_transparent unspecified

Member functions

operator()
returns the quotient of two arguments
(public member function)

std::divides<void>:: operator()

template < class T, class U >

constexpr auto operator ( ) ( T && lhs, U && rhs ) const

- > decltype ( std:: forward < T > ( lhs ) / std:: forward < U > ( rhs ) ) ;

Returns the quotient of lhs and rhs .

Parameters

lhs, rhs - values to divide

Return value

std:: forward < T > ( lhs ) / std:: forward < U > ( rhs ) .

Example

Run this code 
#include <complex>
#include <functional>
#include <iostream>
 
int main()
{
    auto complex_divides = std::divides<void>{}; // “void” can be omitted
    constexpr std::complex z1{8.0, 4.0}, z2{1.0, 2.0};
 
    std::cout << std::showpos
              << complex_divides(z1, z2) << ' ' << z1 / z2 << '\n'
              << complex_divides(z1, 5.) << ' ' << z1 / 5. << '\n'
              << complex_divides(6., z2) << ' ' << 6. / z2 << '\n';
}

Output: 

(+3.2,-2.4) (+3.2,-2.4)
(+1.6,+0.8) (+1.6,+0.8)
(+1.2,-2.4) (+1.2,-2.4)
