| Feb 14, 2015 at 14:16 | comment | added | MightyPork | You're right, I want to display a "real time" value. I hoped there'd be a way to do it without keeping history, but that'll probably indeed be the easiest way. | |

| Feb 14, 2015 at 13:45 | comment | added | Rolf Kreibaum | I guess that is mostly a question of programming, not of math. Saving that stream of numbers should (at about 0.1kib/data point) only take 50mib per year. Keeping all the past values doesn't really seem like a problem. (And may allow you to do exiting stuff later) Unless you want to display a continuously updating number somewhere in your home, the naive, unoptimized algorithm shouldn't be a problem. (And a decent math library should allow you to average a billion numbers) | |
