A few questions:
- Do you think you could post a notice when you have the wrappers done? I'm
very interested in this.
- How does this compare to gmpy?
- Do you have any plans to bind this into Numeric? That would be absolutely
fantastic. One of the things which keeps us bound to Mathematica here is the
need for arbitrary precision algorithms. With Numeric being extended to
arbitrary precision, we'd have a great system.
- Have you looked at http://more.btexact.com/people/briggsk2/XR.html? Do you
know how they compare?
- And http://www.nersc.gov/~dhbailey/mpdist/mpdist.html? This one is supposed
to be first rate.
I'd love to have the ability not only to define extended/arbitrary precision
scalars, but especially to have them carry over to Numeric. One could then
develop a difficult algorithm in arbitrary precision and then move it over to
only extended (or even normal) precision once everything is working reliably.
It would be great if you could post on your progress on this (or mail me
directly: fperez _at_ colorado . edu ).
