Member functions
| 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)
