Very nice and very cool indeed! Thanks a lot Andrew! This seems to be a nice (also because much lighter) competitor to the Sage module for many numerical computations. I will check it as soon as I can.
Best regards,

Yes, I did look at the Sage module, and was daunted. Calculyx is for back-of-envelope stuff. Actually it can do some quite complicated calculations:

\sum_{k=0}^{\infty}\frac{(-1)^{k}}{2^{k+1}}\sum_{n=0}^{k}(-1)^{n}\binom{k}{n}\frac{1}{(k-n)!}

(a laborious way of calculating 1/e) is about the most complicated I've included in the documentation, but you would never use it for serious number crunching. LyX Document
