[seqfan] Re: Large English integer names: Mathematica vs. num2words

[hv at crypt.org]

I think words are more the expertise of dictionaries than of either
Mathematica or Python.

There is useful information at [1] including a list of which dictionaries
include each of the primary names, and an explanation of Conway and Guy's
extended naming scheme; there is additional historical information at [2].

:Michael Branicky and I have just been discussing this because I had found some issues in one of his OEIS b-files. He had used the Python script "num2words" and when I compared the Mathematica vs. the num2words 10^3n names, I found 22 discrepancies up to 10^303. Here they are (power of ten, first word is Mathematica, second is num2words):

:Of course I'm going with the Mathematica versions as being the correct ones. Maybe Python users can request a fix.
