Hi Fredrik, Congratulations. That looks fantastic.
I see you now even have elliptic functions! Can I ask you a question. I haven't been following your blog (but should have). Perhaps you can point me to a post if you already deal with this somewhere. However, I am interested to know how you deal with computation of transcendental functions in general. I presume you make use of power series expansions for some of them. Do you ever have the situation where you have to multiply, or exponentiate power series, etc? If so, how do you deal with the accuracy issues in that case? My knowledge of such things is woefully inadequate. Bill.
