numbers in the example for the task (deprecated)
For 10,000 primes (as shown by the example in the Rosetta Code task), my numbers (using the REXX program) don't match those shown:
For 10000 primes used in this study: H= 80000 prime 10001 is: 84327 digit 1 ──► 1 has a count of: 281, frequency of: 2.81%. digit 1 ──► 3 has a count of: 1094, frequency of: 10.94%. digit 1 ──► 7 has a count of: 697, frequency of: 6.97%. digit 1 ──► 9 has a count of: 308, frequency of: 3.08%. digit 3 ──► 1 has a count of: 417, frequency of: 4.17%. digit 3 ──► 3 has a count of: 236, frequency of: 2.36%. digit 3 ──► 7 has a count of: 588, frequency of: 5.88%. digit 3 ──► 9 has a count of: 719, frequency of: 7.19%. digit 7 ──► 1 has a count of: 512, frequency of: 5.12%. digit 7 ──► 3 has a count of: 578, frequency of: 5.78%. digit 7 ──► 7 has a count of: 254, frequency of: 2.54%. digit 7 ──► 9 has a count of: 1059, frequency of: 10.59%. digit 9 ──► 1 has a count of: 1170, frequency of: 11.70%. digit 9 ──► 3 has a count of: 485, frequency of: 4.85%. digit 9 ──► 7 has a count of: 431, frequency of: 4.31%. digit 9 ──► 9 has a count of: 302, frequency of: 3.02%.
Does anyone else match either set of numbers for 10,000 primes? -- Gerard Schildberger (talk) 22:32, 21 March 2016 (UTC)
Never mind, I found the problem (had to do with the calculation of the upper bound for the sieve). I did think it strange that my calculations for 1,000,000 primes was correct, but not for 10,000. -- Gerard Schildberger (talk) 23:42, 21 March 2016 (UTC)
I get a different result. Also, prime 10001 is 104759. Prime 8220 is 84327. Prime 0 is 2. So that's probably your issue. --Rdm (talk) 22:42, 21 March 2016 (UTC)
- The REXX language (usually) starts out an index with unity, not zero. -- Gerard Schildberger (talk) 23:49, 21 March 2016 (UTC)
Pascal results also match the numbers given in the example. --G.Brougnard (talk) 22:48, 21 March 2016 (UTC)
- And also, it doesn't show the transitions involving the prime number 3 and the number 5. -- Gerard Schildberger (talk) 00:30, 22 March 2016 (UTC)
