U+2260 Not Equal To
U+2260 was added in Unicode version 1.1 in 1993. It belongs to the block Mathematical Operators in the Basic Multilingual Plane.
This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is a canonical composition of the glyphs Equals Sign, Combining Long Solidus Overlay. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored. If its East Asian Width is “narrow”, U+2260 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The CLDR project calls this character “not equal” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: equal, inequality, inequation, not.
The Wikipedia has the following information about this codepoint:
In mathematics, an inequation is a statement that an inequality holds between two values. It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation. Some examples of inequations are:
In some cases, the term "inequation" can be considered synonymous to the term "inequality", while in other cases, an inequation is reserved only for statements whose inequality relation is "not equal to" (≠).
