U+2244 NOT ASYMPTOTICALLY EQUAL TO

U+2244 was added to Unicode in version 1.1 (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 ≃ ̸. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. In text U+2244 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 mathematical analysis, asymptotic analysis is a method of describing limiting behavior. The methodology has applications across science. Examples are

  • In applied mathematics, asymptotic analysis is used to build numerical methods to approximate equation solutions.
  • in computer science in the analysis of algorithms, considering the performance of algorithms when applied to very large input datasets.
  • the behavior of physical systems when they are very large, an example being Statistical mechanics.
  • in accident analysis when identifying the causation of crash through count modeling with large number of crash counts in a given time and space.

The simplest example, when considering a function f(n), is when there is a need to describe its properties as n becomes very large. Thus, if f(n) = n2+3n, the term 3n becomes insignificant compared to n2, when n is very large. The function f(n) is said to be "asymptotically equivalent to n2 as n → ∞", and this is written symbolically as f(n) ~ n2.
