[–] imaqtpie@lemmy.myserv.one 3 points 2 years ago (1 child) Are "Iffs" a thing? I've been missing out. permalink fedilink source parent hideshow 2 child comments replies: [–] Shapillon@lemmy.world 2 points 2 years ago* (last edited 2 years ago) (2 children) iff is the shorthand for "if and only if". If you said "if it is a horse it has hooves" you can infer "all horses have hooves" but not that "all hooved creatures are horses". Otoh if you said "iff a polygon has 3 sides, it is a triangle" you can infer that all polygons that have 3 sides are triangles and that there are no other ways to make triangles. edit: This was typed by sleep deprived me, I tried to fix it. permalink fedilink source parent hideshow 4 child comments replies: [–] imaqtpie@lemmy.myserv.one 2 points 2 years ago (1 child) Cool, TIL permalink fedilink source parent hideshow 2 child comments replies: [–] Shapillon@lemmy.world 2 points 2 years ago (1 child) Omg I have no clue how you understood anything from my previous comment. It was such a mess lmao permalink fedilink source parent hideshow 2 child comments replies: [–] imaqtpie@lemmy.myserv.one 2 points 2 years ago* (last edited 2 years ago) Well I mostly was already familiar with "if and only if" terminology from some math class many years ago. So once you said iff stands for "if and only if" I didn't really look too close at the rest of your comment because I felt like I already understood. permalink fedilink source parent [+] imaqtpie@lemmy.myserv.one 1 point 2 years ago [deleted] permalink fedilink source parent
