As a programmer I’m annoyed at mismatching parentheses.
Is there a saner notation 😢
I never saw that notation. I learned to write
]a, b]instead.That’s French notation iirc. More intuitive imo, but its parentheses are also mismatching.
Yeah, they do mismatch. I just mentioned it because I was unfamiliar with the notation in the image. You could also write
{x ∊ ℝ : x > a ⋀ x ≤ b}or[a, b]\{a}
terrible for bad handwriting, otherwise practical
[a,b) is commonly called “half open” in the database world, so my first instinct is to call (a,b] half closed. Sounds weird though. Inverse half open?
