# U+2A52 LOGICAL OR WITH DOT ABOVE

U+2A52 was added to Unicode in version 3.2 (2002). It belongs to the block U+2A00 to U+2AFF Supplemental Mathematical Operators 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.

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is not mirrored. In text U+2A52 behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

Exclusive or or exclusive disjunction is a logical operation that is true if and only if its arguments differ (one is true, the other is false).

It is symbolized by the prefix operator J and by the infix operators XOR ( or ), EOR, EXOR, , , , , ↮ {displaystyle leftrightarrow } , and . The negation of XOR is the logical biconditional, which yields true if and only if the two inputs are the same.

It gains the name "exclusive or" because the meaning of "or" is ambiguous when both operands are true; the exclusive or operator excludes that case. This is sometimes thought of as "one or the other but not both". This could be written as "A or B, but not, A and B".

Since it is associative, it may be considered to be an n-ary operator which is true if and only if an odd number of arguments are true. That is, a XOR b XOR ... may be treated as XOR(a,b,...).
