[–] agamemnonymous@sh.itjust.works 12 points 1 month ago (2 children) As a former math major, it annoys me because 0 and Ø are different concepts. permalink fedilink source parent hideshow 4 child comments replies: [–] sp3ctr4l@lemmy.dbzer0.com 5 points 1 month ago Wait, what. ... oh no. Nope. Nope, not going back to set theory, it is 105F / ~40C right now, highly confident I would give myself heat stroke. permalink fedilink source parent [–] folekaule@lemmy.world 5 points 1 month ago Your comment led me down a bit of a rabbit hole and I found this on Wikipedia: When writing in languages such as Danish and Norwegian, where the empty set character may be confused with the alphabetic letter Ø (as when using the symbol in linguistics), the Unicode character U+29B0 ⦰ REVERSED EMPTY SET may be used instead. It also mentions what you are alluding to: In the past, "0" (the numeral zero) was occasionally used as a symbol for the empty set, but this is now considered to be an improper use of notation. And, as a programmer, don't get me started on nulls...or undefined...or truthyness. permalink fedilink source parent
