std::divides::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

Return value

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

[edit] Example

#include #include #include   int main() { auto complex_divides = std::divides{}; // “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)
