I was reading some notes about PI and as a typical IT guy I have decided to test some algorithm but before I wanted to check number quantity per decimal length (explanation in next paragraph). For resource I have used: http://www.piday.org/million.php there I took 1000000 decimal and wrote a small application to see how many times 1,2,3,4,5,6,7,8,9 and 0 numbers are used. And I get some interesting results and wanted to share with you.
i.e. in first 100000 decimal total 9999 0(zero) exist. Generally total number * 100000 very close to decimal length/10;
or
total of 1000000 decimal: 4499934
total of 100000 decimal: 449333
total of 10000 decimal: 44894
total of 1000 decimal: 4476
total of 100 decimal: 477
total of 10 decimal: 41
Do you think it can be interesting? If someone wants I can share full results. (Can be useless information but I was doing just for fun, so dont judge me:))
