I don't think the double-long types are guaranteed to be usable as
value-based template parameters, since they're not officially in C++ (yet).
That's why I didn't use them in Boost.CRC.  (That was several years ago, so
maybe that changed.  Also, someone else told me that, I never checked it
myself.)
