thanks, I can certainly make use of your library.
I have a nitpick with the docs, though: Could you clarify *which* Zeta function
the zetaTwo and zetaThree constants refer to? My guess is the Riemann Zeta
function and that seems to match with the values you provide.
But there are many other Zeta functions as well. (For example,
http://mathworld.wolfram.com/ZetaFunction.html gives links to eight Zeta
functions.) So it would help to avoid misunderstandings if you identified the
Zeta function you refer to.
Second, there is an error and a typo in the comment following the definition
of zetaTwo:
// Zeta(2) or Pi^(2/6) = sum(1/n**2, n=1..infinity
^^^^^^^^ ^^^
This should read
// Zeta(2) or Pi^2 / 6 = sum(1/n**2, n=1..infinity)
