The continued fraction domain is using Moebius transforms internally (z -> (az+b)/(cz+d)) like Gosper. I wasn't specifically aware of his work at the time, though.
The main issue is not in converting a particular value to a continued fraction, which is easy, but rather to construct a c.f. out of a stream of convergents, e.g. obtained as the result of arithmetic on two other c.f.s. -- Stephen On Thu, Dec 06, 2007 at 09:52:19PM +0100, Martin Rubey wrote: > Stephen Watt <[EMAIL PROTECTED]> writes: > > > Dear Martin, > > > > The quick answer is that I don't remember off the top of my head what > > restrictions exist on the domain parameter. > > > > I'm on the road now (just 10 minutes ago checked into my hotel) and so > > don't have access to a couple of things that would refresh my memory. > > Stephen, do you happen to remember whether you have been aware of Gosper's > algorithms for continued fractions?
