U+27CF Squared Logical Or

U+27CF wurde in Version 6.0 in 2010 zu Unicode hinzugefügt. Er gehört zum Block U+27C0 bis U+27EF Miscellaneous Mathematical Symbols-A in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Math Symbol und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Das Schriftzeichen ist auch bekannt als box max.

Das Zeichen ist keine Zusammensetzung. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text handelt es als Other Neutral. Bei einem Richtungswechsel wird es nicht gespiegelt. Das Wort, das U+27CF mit ähnlichen Zeichen bildet, verbietet in sich Zeilenumbrüche.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

In logic, disjunction, also known as logical disjunction or logical or or logical addition or inclusive disjunction, is a logical connective typically notated as and read aloud as "or". For instance, the English language sentence "it is sunny or it is warm" can be represented in logic using the disjunctive formula SW, assuming that S abbreviates "it is sunny" and W abbreviates "it is warm".

In classical logic, disjunction is given a truth functional semantics according to which a formula ϕψ is true unless both ϕ and ψ are false. Because this semantics allows a disjunctive formula to be true when both of its disjuncts are true, it is an inclusive interpretation of disjunction, in contrast with exclusive disjunction. Classical proof theoretical treatments are often given in terms of rules such as disjunction introduction and disjunction elimination. Disjunction has also been given numerous non-classical treatments, motivated by problems including Aristotle's sea battle argument, Heisenberg's uncertainty principle, as well as the numerous mismatches between classical disjunction and its nearest equivalents in natural languages.

An operand of a disjunction is a disjunct.
