std::divides is a functor that encapsulates operator/. The functor to perform a multiplication on a range is std::multiplies.

Example


#include <vector>

#include <algorithm

#include <numeric>



//From http://www.richelbilderbeek.nl/CppHalve.htm

void Halve(std::vector<double>& v)

{

  std::transform(v.begin(),v.end(),v.begin(),

    std::bind2nd(std::divides<double>(),2.0));    

}
