#include <ratio>
#include <iostream>
using namespace std;
int main()
{
typedef ratio<5,3> FiveThirds;
cout << FiveThirds::num << "/" << FiveThirds::den << endl;
typedef ratio<25, 15> AlsoFiveThirds;
cout << AlsoFiveThirds::num << "/" << AlsoFiveThirds::den << endl;
cout<<boolalpha<< std::ratio_not_equal<ratio<5, 3>, AlsoFiveThirds>::value << endl;
return 0;
}
When I run this code in VS2012, or VS2013 preview I get true meaning 5/3 != 25/15. ratio_equal also yeilds a false result but ratio_less_equal and ratio_greater_equal seems to get the answer correct.
Am I failing to understand something simple or is this a bug?
Thank you
