SAR is calculated incorrectly

On the page List of common resolutions you can see 372x240 being listed as 17:11. This seems to be caused by some rounding error, it's supposed to be 31:20. At time of writing just default calculated by this template as X/Y, so it's not the page itself that has used an incorrect override. Philipborg (talk) 09:40, 5 March 2024 (UTC)

That’s done by {{resratio}}. It doesn’t support 31:20 (yet), because it’s not a common aspect ratio – whereas 17:11 is “common” in American paper formats: — Christoph Päper 10:33, 5 March 2024 (UTC)
