The Mathematical Symbol "Not Greater-Than (≯)"
The "Not Greater-Than" Symbol (≯)
The ≯ symbol is a mathematical notation used to indicate that one number is not greater than another. In other words, it expresses the relationship between two numbers when one is either less than or equal to the other, but not strictly greater than the other.
Understanding ≯
The ≯ symbol combines the concepts of the traditional less than or equal to (≤) and not equal to (≠) symbols. Essentially, if "a ≯ b", it means that "a" is not strictly greater than "b", and could be equal to or less than "b".
Example 1: Basic Use
Consider the numbers 5 and 7. We can say: \[ 5 ≯ 7 \] This statement means that 5 is not greater than 7, which is accurate.
Example 2: Equality
Using the same symbol, consider the numbers 8 and 8: \[ 8 ≯ 8 \] In this context, the statement means that 8 is not greater than 8, which implies equality.
Common Usage of ≯
The ≯ symbol is primarily used in:
- Mathematics: It is a standard notation in mathematical equations and expressions, especially when discussing inequalities.
- Programming: Some programming languages and software tools utilize this symbol or its equivalent for specific comparison operations.
In summary, the ≯ symbol offers a concise way to depict the relationship between numbers in the context of inequalities. Being familiar with this and other related symbols is beneficial for individuals working with mathematics or coding.

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 8815. 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: "\226F";} </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+226F. 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 |
|---|---|
| 226F [Hold down Alt] [Press x] | ≯ (The 226F turns into ≯. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u226F" document.write("My symbol: " + str) | My symbol: ≯ |
