U+27CF Squared Logical Or

U+27CF was added in Unicode version 6.0 in 2010. It belongs to the block U+27C0 to U+27EF Miscellaneous Mathematical Symbols-A in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script. Znak jest również znany jako box max.

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+27CF forms with similar adjacent characters prevents a line break inside it.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

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.
