NameNot sign
Unicode numberU+00AC
CategoryLatin-1 Supplement2. Latin-1 punctuation and symbols
DescriptionThe Unicode character ¬, or U+00AC, is known as the "Not Sign". It belongs to the "Latin-1 Supplement" block, which is used to extend the original ASCII character set with additional characters for use in Western languages. This character falls under the "Symbol, Math" category. Visually, it represents a horizontal line with a descending vertical line on the right end, forming a kind of hooked stroke. In mathematics and logic, the not sign is used as a negation operator: it inverts the truth value of the expression or statement that follows it. For example, if A is true, then ¬A (read as "not A") is false, and vice versa. It is also used in some programming languages with a similar purpose, to perform logical NOT operations. Its specific meaning can depend on the context in which it is used.
