U+2271 Neither Greater-Than Nor Equal To

U+2271 was added to Unicode in version 1.1 (1993). It belongs to the block U+2200 to U+22FF 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 a Canonical composition of the glyphs Glyph for U+2265 Greater-Than Or Equal To, Glyph for U+0338 Combining Long Solidus Overlay. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. Its corresponding mirrored glyph is Glyph for U+2270 Neither Less-Than Nor Equal To. In text U+2271 behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. There are several different notations used to represent different kinds of inequalities:

  • The notation a < b means that a is less than b.
  • The notation a > b means that a is greater than b.

In either case, a is not equal to b. These relations are known as strict inequalities, meaning that a is strictly less than or strictly greater than b. Equivalence is excluded.

In contrast to strict inequalities, there are two types of inequality relations that are not strict:

  • The notation ab or ab means that a is less than or equal to b (or, equivalently, at most b, or not greater than b).
  • The notation ab or ab means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).

The relation not greater than can also be represented by ab, the symbol for "greater than" bisected by a slash, "not". The same is true for not less than and ab.

The notation ab means that a is not equal to b; this inequation sometimes is considered a form of strict inequality. It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.

In engineering sciences, less formal use of the notation is to state that one quantity is "much greater" than another, normally by several orders of magnitude.

  • The notation ab means that a is much less than b.
  • The notation ab means that a is much greater than b.

This implies that the lesser value can be neglected with little effect on the accuracy of an approximation (such as the case of ultrarelativistic limit in physics).

In all of the cases above, any two symbols mirroring each other are symmetrical; a < b and b > a are equivalent, etc.
