Le 18/12/2015 00:45, Jeffrey Brown badly needs :

the first thousand or so digits of irrational numbers? In base 12?

Well, I wonder why not in base 314159? It would be much more Mystical, and making Music out of it would not be more lousy than in any other base.
Anyway...

Conversion from one base to another of an integer is a simple student exercise. But of a fraction, perhaps infinite, requires more work. I did it some centuries ago,  if you want some co-recursive fun, find my Braga School participant delirium: "The most Unreliable Technique in the World to Compute Pi", still somewhere among my files ( https://karczmarczuk.users.greyc.fr/arpap/lazypi.pdf ).  I never thought I would recommend it to anybody...

Now, I would not call my exercice a "canned routine"...
