Combinations and permutation limits on Calculators  JaSon  03022003 I've noticed that old Hp calculators and Kinpo(recent HP and TIs) can calculate combinations to the full range the calculator can display ie. any combination with an answer less than 9e100 or 9e499 (depending on the calc), But all Casio and Sharp calculators (even a graphing casio)cannot calculate any combination larger than 104C52 which eguals 1.583065848e30, I get an error message trying to calculate 106C53. I can however calculate 114C51=8.27e32, 124C50=1.49e35, 134C49=1.16e37... and so on increasing the number of objects by 10 and decreasing the number taken by 1. I don't see where there would be a similar limit in the calculation n!/((nr)!*r!) for all these combinations.

i've just tried out a bunch of casio machines and none can perform 106C53, presumably because the intermediate 106!/53! is too large when calculated as 106*105*...*54, is about 1e100. Re: Combinations and permutation limits on Calculators  Paul Brogger  03032003 The 42s appears to have the same capabilities as the 32S/Sii in this respect. Either handles the examples mentioned, and up to 500C240 (7.83E148), which is as far as I've got time to go, right now.
