To me , it just doesn't "fit" with the rest of the library , I can't explain it more than that :) > I actually use it and find it very useful.

Ideally we have some sort of state that we can pass to the nextprime function , I suppose we could add it to MPIR now (pointer to a structure), and we could fill in the details later. > Right now unless you dig into the code it is hard to tell what the two > current prime functions really do.

We can add specific algorithms later , it is something I plan to do , if everyone else thinks its a good idea. Perhaps we should set up a new directory for future extentions , where we can thrash out the details of algorithms and interfaces. Until you actually write and use the code in a few situations you can never be sure what is the "best" way to do it. If we have code as well then users can give us feedback on what really get used. > If someone > is trying to do work that needs to be repeatable it would be good to > have a way for people to say, "Use MPIR with this is_prime/prob_prime > function using these parameters" > The new functions are all deterministic given the same random state. > Jeff. > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "mpir-devel" group.
