std::divides<void>
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.
Nested types
| Nested 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
#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)
