https://github.com/MicrosoftDocs/cpp-docs/blob/master/docs/c... > Multiple function templates that match the argument list of a function call can be available. C++ defines a partial ordering of function templates to specify which function should be called. The ordering is partial because there can be some templates that are considered equally specialized. > The compiler chooses the most specialized template function available from the possible matches. And it goes on to give an example.
