To completely understand your suggestion,
I tried to write some sample code,
specializing rational_cast_helper for, say, rational<int>.
I did not succeed, however.
Maybe it is just because of the definciences of Visual C++.
Can you post a code example how
specialization for rational<int> should look like?

Thank you,
