The Mathematical Symbol "Contains with Vertical Bar At End of Horizontal Stroke (⋻)"

The ⋻ Symbol in Mathematics: Contains with Vertical Bar At End of Horizontal Stroke

Mathematics is rich with symbols, each offering a unique expression or relation. One of the more specialized symbols is the ⋻, which denotes "Contains with Vertical Bar At End of Horizontal Stroke". This article provides insights into this symbol's interpretation and examples of its use.

Usage

The ⋻ symbol is a variant of the 'contains' or 'element of' symbol found in set theory. While the traditional symbol indicates membership of an element in a set, this variant adds a level of specificity or nuance. The exact interpretation might vary depending on the context or the particular mathematical framework in question.

Examples

• Example 1: Given a specialized set context:
  \( a ⋻ S \)
  This might mean that \( a \) has a special kind of membership in the set \( S \), perhaps satisfying certain additional conditions or criteria.
• Example 2: In a refined logical or set-theoretic framework:
  \( x ⋻ T \)
  Here, \( x \) might be related to the set \( T \) under a unique membership rule, distinguished from the standard element-of relation.

In summary, while the ⋻ symbol is less commonplace than many mathematical notations, its presence underscores the depth and nuance of mathematical relations. Recognizing its significance helps in navigating advanced mathematical contexts with precision and clarity.

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 8955. 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: &#8955;</b>	My symbol: ⋻

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

HTML Text	Output
<b>My symbol: &xnis;</b>	My symbol: ⋻

(Method 5) Use the CSS Code (for webpages).

CSS and HTML Text	Output
<style> span:after { content: "\22FB";} </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: &#x22FB;</b>	My symbol: ⋻

On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22FB 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+22FB. 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
22FB [Hold down Alt] [Press x]	⋻ (The 22FB turns into ⋻. Note that you can omit any leading zeros.)

In JavaScript, the syntax is \uXXXX. So, our example would be \u22FB. (Note that the format is 4 hexadecimal characters.)

JavaScript Text	Output
let str = "\u22FB" document.write("My symbol: " + str)	My symbol: ⋻
