The Mathematical Symbol "Greater-Than But Not Equal To (≩)"
The ≩ Symbol in Mathematics: Greater-Than But Not Equal To
Mathematics has a diverse collection of symbols, each with specific meanings and uses. One such symbol is ≩, which stands for "Greater-Than But Not Equal To". This article sheds light on its usage and provides illustrative examples.
Usage
The ≩ symbol is used to represent a unique relational scenario between two quantities. It's not merely stating that one quantity is greater than the other but additionally emphasizing that the two are not equal in any conventional sense.
Examples
- Example 1: Comparing Numbers:
If we have two numbers \( a \) and \( b \), and \( a \) is strictly larger than \( b \) but not identically equal to any other number that might be considered equivalent to \( b \), we can express this relationship as \( a ≩ b \). - Example 2: Inequalities in Algebra:
Let's consider an algebraic expression \( f(x) \) and a constant \( c \). If \( f(x) \) is strictly greater than \( c \) but not identically equal to any other value which could be considered equivalent to \( c \), then we can denote this relationship as \( f(x) ≩ c \).
To wrap up, the ≩ symbol offers a refined way to articulate a specific type of inequality. It provides more information than a simple "greater-than" sign, emphasizing a strict inequality and exclusion of any other equivalent values. Recognizing its distinct meaning can be vital in nuanced mathematical discussions.

Codes for the ≩ Symbol
| The Symbol | ≩ | |
| Alt Code | Alt 8809 | |
| HTML Code | ≩ | |
| HTML Entity | ≩ | |
| CSS Code | \2269 | |
| Hex Code | ≩ | |
| Unicode | U+2269 |
How To Insert the ≩ Symbol
(Method 1) Copy and paste the symbol.
The easiest way to get the ≩ symbol is to copy and paste it into your document.Bear in mind that this is a UTF-8 encoded character. It must be encoded as UTF-8 at all stages (copying, replacing, editing, pasting), otherwise it will render as random characters or the dreaded �.
(Method 2) Use the "Alt Code."
If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type 8809. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)(Method 3) Use the HTML Decimal Code (for webpages).
| HTML Text | Output |
|---|---|
| <b>My symbol: ≩</b> | My symbol: ≩ |
(Method 4) Use the HTML Entity Code (for webpages).
| HTML Text | Output |
|---|---|
| <b>My symbol: ≩</b> | My symbol: ≩ |
(Method 5) Use the CSS Code (for webpages).
| CSS and HTML Text | Output |
|---|---|
|
<style> span:after { content: "\2269";} </style> <span>My symbol:</span> | My symbol: ≩ |
(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).
| HTML Text | Output |
|---|---|
| <b>My symbol: ≩</b> | My symbol: ≩ |
| JavaScript Text |
|---|
|
const x = "0x"+"E9" ctx.fillText(String.fromCodePoint(x), 5, 5); |
| Output |
≩ |
(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).
The Unicode for ≩ is U+2269. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:| Type | Output |
|---|---|
| 2269 [Hold down Alt] [Press x] | ≩ (The 2269 turns into ≩. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u2269" document.write("My symbol: " + str) | My symbol: ≩ |
