#include <string>

int main()
{
    double randDouble = 1245.432;
    std::wstring stringDouble = std::to_wstring(randDouble);
}

When I compile this in Visual Studio 2010 I get this error

Error 1 error C2668: ‘std::to_wstring’ : ambiguous call to overloaded
function 6

Can someone please explain to me why the compiler is confused and what am I doing wrong?
