digits of pi

Posted 9 years ago

I am playing with the digits of pi ...

I use 10.1 with 2.4Ghz MacMini, 8 G memory ...

I am up to 300,000,000 digits (820 seconds timing), (working on 400,000,000 now) previously, I had tried a billion digits, but I aborted ... it might be because the computer went to sleep (I had not set preferences to not sleep)

... is there a physical limit with my machine? or is it just a matter of waiting a long time?

... I have never used "Export" -- I am assuming that I can Export and then Import the digits (so I don't have to rerun the calculation each time I open the file) I did try Export with 300,000,000 digits but it seemed to take a long time, so I aborted

I am assuming that I am going to run into a wall getting to a billion digits ... any suggestions?

Simon --

digitsPi  =  Delete[ RealDigits[ N[ Pi,1000000000 ], -1]     will give a data list

Export[ "piBillion.dat", digitsPi]   will give a usable data file

but the damn thing is 1 G big, and not email-able

so ... what to do?
