While interesting this is just… wrong. Imagine a world where:

- I tell people I’m 50 years old but I’m really just 49 1/2

- My phone says it’s Jan 7th but it’s really afternoon on Jan 6th

- My coworker says they’re a sr engineer because they’ve been told that they’ll definitely be promoted soon

Rounding shouldn’t be applied everywhere. Some things in life are supposed to use a floor function; common sense applies and most folks intuitively know that 1:00pm means ‘between 1:00 and 1:01pm’.

TFA goes into the author's opinion around when to floor and when to round, and notes that "hours" is the largest interval where rounding feels right.
