That's the part that has the simple mnemonic structure. You have to memorize something to remember more. As undergraduates, a couple of us computed e to 9845 decimals. That was the amount that would fit twice into the 20000 digits of the IBM 1620 we did it on while leaving room for the add table and the program. We told Professor Mielke what we had done and he showed us a nice fresh paper in Mathematical Tables and Other Aids to Computation, by someone at the David Taylor Model Basin (whose name I've been trying to remember since this thread began) about the calculation of pi to 100,000 decimals. A footnote offhandedly announced that they had also calculated e to the same precision "by the obvious algorithm". I have a nice letter from him and a reprint of the MTOC paper. And a listing of our results which confirmed his first ten thousand places. dan herrick herrickd@iccgcc.decnet.ab.com
