You probably have already thought of this but here is a work around anyway

#include <iostream>

int main()                                                                   {
        for ( double i = 1.0; i < 3.1; i += 0.1 )
        {
                cout << "Double:" << (i - 1.0) << ", Integer:" << ((int) i - 1)
<< endl;
        }
        return (0);                                                          }
