Talk:Relative errors of small EDOs

(WIP) Relative Errors of Small Edos

I did a change to the upper table to right-align the numbers, I hope that's okay. Here some (hopefully helpful) suggestions:

• leave out the repetitive /1 in the headings
• leave out the column for prime 2
• switch from permille with one decimal place to the more common percent with two decimal places

Best regards --Xenwolf (talk) 07:26, 14 May 2020 (UTC)

Thx. No idea how you did it.

> leave out the repetitive /1 in the headings

> leave out the column for prime 2

Although this article is about edos, the method is valid for all rank-1 temperaments. For non-octave temperaments, the errors of, for example, 3/1 and 3/2 are different. Maybe I'll do ed3, ed5, etc. in the future. That's the reason why the /1 and prime 2 are there.

> percent

I'll do the switch after I fill it all up to see if it looks better. FloraC (talk) 15:15, 14 May 2020 (UTC)

Maybe I can help you with this, I'm a professional programmer who can automate this with Perl or Python. I'd also hand you the script for further adaption then ... Please tell me if this sounds right to you. --Xenwolf (talk) 18:49, 14 May 2020 (UTC)

Nice.

I don't suppose your script generates those values (cuz I did so in C), just doing with the table, right? FloraC (talk) 02:52, 15 May 2020 (UTC)

Such a script would also generate the values. --Xenwolf (talk) 05:50, 15 May 2020 (UTC)

Let's do it then. FloraC (talk) 12:04, 15 May 2020 (UTC)

permille vs. percent

Comparison of permille and percent formatting below. I restricted the table to only a few columns and rows

Edo Relative Errors (in ‰) 3/1 5/1 7/1 11/1 13/1 9 264.7 -102.6 266.2 134.9 304.0 10 -150.4 219.3 73.5 -405.7 4.4 11 434.6 -458.8 -119.1 53.7 -295.2 12 19.6 -136.9 -311.7 -486.8 405.3 13 -395.5 185.1 495.6 -27.4 105.7 14 189.5 -493.0 303.0 432.0 -193.8

Edo Relative Errors (in %) 3/1 5/1 7/1 11/1 13/1 9 -26.47 10.26 -26.62 -13.49 -30.40 10 15.04 -21.93 -7.35 40.57 -0.44 11 -43.46 45.88 11.91 -5.37 29.52 12 -1.96 13.69 31.17 48.68 -40.53 13 39.55 -18.51 -49.56 2.74 -10.57 14 -18.95 49.30 -30.30 -43.20 19.38

To me the percent values look more familiar and the grouping is better (at maximum pairs of numbers) --Xenwolf (talk) 19:07, 15 May 2020 (UTC)
