Calculation of pi on many machines

[Dave Britten]

Very nice comparison! I especially like the inclusion of the Casio fx-6300G, as these old Casios are great to program (I sometimes use an old Casio to prototype an algorithm before implementing on an RPN calculator), and the "old world" models up through the fx-9700GE and cfx-9800G - i.e. the "Defm" models - have very easy-to-use indirect addressing, as demonstrated here. However, there is a bug you have to watch out for on the fx-6300G when using indirect addressing in combination with comparison tests:
