Greater-Than But Not Equal To

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.

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: &#8809;</b>	My symbol: ≩

(Method 4) Use the HTML Entity Code (for webpages).

HTML Text	Output
<b>My symbol: &gnE;</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: &#x2269;</b>	My symbol: ≩

On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2269 to place the ≩ symbol on your canvas. For example:

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.)

In JavaScript, the syntax is \uXXXX. So, our example would be \u2269. (Note that the format is 4 hexadecimal characters.)

JavaScript Text	Output
let str = "\u2269" document.write("My symbol: " + str)	My symbol: ≩
