I’d say one point thirty-two. As others noted, much depends on geography.

Personally, I say the “actual” number up to 3 or 4 decimal places, with a lot of the reason depending on the specific context. If I had to asses, I’d say I say the “whole” number in over 50% of cases for 3 digits, and in about 10% for 4 digits. Anything over 4 decimal places and I fall back to individual digits.

It’s not meaningless - it moves the comment/post a bit higher for others to see on some sorting options. It just isn’t summated per user and obsessed over.

outright confirmed the exclusion […] Notably, he didn’t specify whether or not

Yeah, that’s what “outright” means all right.
