I would be indebted to colleagues who may be able to assist me with
either of the following:

1) Sources detailing Al-Kashi's (1424) calculation of pi (using a
regular polygon having 805, 306, 368 sides) which was correct to
16 places of decimals.

2) John L Berggren's e-mail address (who has been involved in the
history of Islamic mathematics).

Many thanks.
