Journal: Affine Arithmetic Library

Journal by sir99
Anyone interested in helping to write an Affine Arithmetic library? It's quite challenging, and requires a good understanding of floating-point math and calculus.

Right now I'm trying to make what I have so far suitable for distribution. I have the basic library and several (mathematical) functions implemented, but I need to go through and implement rounding-error control in all of the functions. My interval arithmetic library is a little more complete. My main focus right now is to make it a little more portable and distributable with autoconf and automake, but I don't have any experience with those.

I do have a neat implicit function grapher that uses the library, but it's rather hackish at the moment, and requires you to use postfix notation. I also have a bit of a testsuite written.

I would love to hear from anybody who's interested in the library. Unfortunately I haven't gotten around to posting the library publically yet, but I'll try to post some pictures generated by the function grapher on my web site some time.

Numeric stability is probably not all that important when you're guessing.
