Hi,
I have found a couple small problems with the documentation for
boost::rational, and I have a question about the design, but I haven't seen
any posts from Paul Moore in the last year. Who maintains boost rational
now?
Small problems:
1. All the members of boost::rational are documented as private.
2. Missing semicolon at the end of the class definition.
Design question:
Why is rational::int_type private? It seems like a fundamental type
associated with rational -- like the value_type of a container, the
value_type of std::complex, the first_type and second_type of std::pair. Why
not make it public?
I've written traits templates pair_traits an nary_traits to provide
compile-time access to the element types and runtime access to the elements
of pair-like and tuple-like types (pair, complex, boost::rational,
boost::interval, boost::tuple, ...) in a uniform manner. It seems strange
that the underlying element type of rational has to be extracted via partial
specialization.
