U+27D8 Large Up Tack
U+27D8 was added in Unicode version 3.2 in 2002. It belongs to the block
This character is a Puntuación matemática and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+27D8 forms with similar adjacent characters prevents a line break inside it.
El Wikipedia tiene la siguiente información acerca de este punto de código:
The up tack or falsum (⊥,
otin LaTeX, U+22A5 in Unicode) is a constant symbol used to represent:
- The truth value 'false', or a logical constant denoting a proposition in logic that is always false (often called "falsum" or "absurdum").
- The bottom element in wheel theory and lattice theory, which also represents absurdum when used for logical semantics
- The bottom type in type theory, which is the bottom element in the subtype relation. This may coincide with the empty type, which represents absurdum under the Curry–Howard correspondence
- The "undefined value" in quantum physics interpretations that reject counterfactual definiteness, as in (r0,⊥)
as well as
- Mixed radix decoding in the APL programming language
The glyph of the up tack appears as an upside-down tee symbol, and as such is sometimes called eet (the word "tee" in reverse). Tee plays a complementary or dual role in many of these theories.
The similar-looking perpendicular symbol (⟂,
perpin LaTeX, U+27C2 in Unicode) is a binary relation symbol used to represent:
- Perpendicularity of lines in geometry
- Orthogonality in linear algebra
- Independence of random variables in probability theory
- Coprimality in number theory
The double tack up symbol (⫫, U+2AEB in Unicode) is a binary relation symbol used to represent:
- Conditional independence of random variables in probability theory
