I have seen this method in use, but it just doesn't work for me. It seems so basic. I have a couple related questions or problems I don't know how to find answers to. The im...

This works fine, but when my templated type is unsigned, I get a warning about how the comparison is always false. This obviously makes sense, but since its templated, I'd like it to be geenric for all data types (signe...
