Just a quick note concerning the rational class- I see in the
documentation that it was decided not to provide a rational
approximation (from double) function as part of the library.

A good public domain implementation of such a function that I have
used previously is at

It allows one to provide a relative error bound on the approximation.
It is in K&R C, but is easily convertible to C++ (just change the
prototype and remove the fabs() declaration).

I think that it would be useful to add a link to this code in the
rational documentation.
