[edit] Member functions
operator()
(public member function)
std::divides<void>::operator()
template< class T, class U >
constexpr auto operator()( T&& lhs, U&& rhs ) const
Returns the quotient of lhs and rhs.
Parameters
lhs, rhs
-
values to divide
Return value
std::forward <T>(lhs) / std::forward <U>(rhs).
[edit] 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)
