[Scilab-users] [EXTERNAL] Count specific values in text file

[Chin Luh Tan]

Hi,



tabul function might help.



sample data download from https://thestarman.pcministry.com/math/pi/picalcs.htm



unzip the https://thestarman.pcministry.com/math/pi/df/pimultdp.zip



following lines do the "counting" job. 



have not tried the millions decimal places, good luck. 





--> data = mgetl('PI25K_DP.TXT'); 



--> data2=strsplit(data);



--> tabul(data2)

ans  =

Hello Philipp 
 
Your suggestion is kind of what I am trying to do, but the text file is not 
a CSV structure. It is just a single, very big number on one row. A small 
chunk: 
 
31415926535897932384626433832795028841971693993751058209749445923078164 etc 
(no spaces between digits) 
 
How best to load the text file and then count the number of occurrences of a 
specific digit (e.g. 1)? At the moment the file essentially contains a very 
big integer. 
 
Interested to see the best method of doing this. 
 
Thanks
