Comment (by kcrisman):
Brief questions:
* When special-casing `n=0`, you have
{{{
return 1
}}}
Will this be a Python int?
* What if `n` is a Python int?
{{{
We can accept Python integers for ``x`` as well::
}}}
* How's speed? I can imagine the sum thing getting slow.
* Am I misreading this? Should it be beta = 1?
{{{
# From Abramowitz & Stegun, (22.3.2) with alpha = beta = 0.
}}}
Oh, I see. [http://people.math.sfu.ca/~cbm/aands/page_775.htm It's
actually (22.3.1)] and maybe this should be in the code with a reference
section.
