I computed the digits of pi using Borwein's method. I used a
divide-and-conquer multiply routine, hand coded in 68020 assembly
language. It was capable of multiplying two 1.25+ million digit
numbers in about 20 minutes on an HP 9000/370 (a 25MHz 68030?).
The computation took a little over three days, at which point I had
the answer in *binary*. :-( The binary to decimal conversion was
no simple task.
I checked my results by performing the same calculation to 2.5+
million digit precision, (9 days) and compared the binaries. The
only independent check has come from David Bailey, whose results
agree with mine to at least 1 million digits (probably.... The
last 100 digits are the same.)
