      [edit]Member functions

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

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

      template<class T,class U>

      constexprauto operator()( T&& lhs, U&& rhs)const

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

      Returns the quotient oflhs andrhs.

      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 omittedconstexprstd::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)
