And given that the submission I just got is over 9000 lines, I'm likely to
change the result until it's unrecognizable in the usual
https://landley.net/toybox/cleanup.html multiple passes way. (Only probably more
of them than usual because 9000 lines.)

I pointed somebody doing the bc stuff at https://bellard.org/libbf/ last week
(Fabrice Bellard just wrote an arbitrary precision floating point library, which
is MIT licensed but maybe if I asked I could get permission from him to use it
under 0BSD), and they said it wasn't compatible with what they were doing.

(99.99% of everything seems to be happy with either 64 bit math or double
precision floating point. There's not usually a lot of call for finding digits
of pi.)

I'm sorry things didn't work out. Thanks for getting the process started.
