The Mathematical Symbol "Curly Logical Or (⋎)"

The ⋎ Symbol in Mathematics: Curly Logical Or

Mathematics and logic are replete with symbols that encode specific meanings, aiding in precise communication. The ⋎ symbol, also known as "Curly Logical Or", is one such notation predominantly found in logical contexts. This article sheds light on its role and significance, underpinned by illustrative examples.

Usage

The ⋎ symbol, with its curly or wavy appearance, represents a variant or a nuanced form of the standard logical "OR" operator. While its specific interpretation can vary depending on the context, it's primarily used to introduce a form of logical disjunction that might have additional implications or conditions compared to the standard "OR".

Examples

• Example 1: In some logical systems or frameworks:
  \( p ⋎ q \)
  This might represent a disjunction where \( p \) or \( q \) is true, but not necessarily both, differentiating it from a standard inclusive "OR".
• Example 2: In advanced logic or set theory contexts:
  \( A ⋎ B \)
  This could denote a union operation with specific conditions or properties that sets it apart from the usual union.

To conclude, the ⋎ symbol, while not as common as the regular logical "OR", serves as a testament to the depth and intricacies of logical and mathematical notations. Recognizing and understanding such symbols can be pivotal in advanced studies or specialized areas of research.

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 8910. 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: &#8910;</b>	My symbol: ⋎

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

HTML Text	Output
<b>My symbol: &cuvee;</b>	My symbol: ⋎

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

CSS and HTML Text	Output
<style> span:after { content: "\22CE";} </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: &#x22CE;</b>	My symbol: ⋎

On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22CE 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+22CE. 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
22CE [Hold down Alt] [Press x]	⋎ (The 22CE turns into ⋎. Note that you can omit any leading zeros.)

In JavaScript, the syntax is \uXXXX. So, our example would be \u22CE. (Note that the format is 4 hexadecimal characters.)

JavaScript Text	Output
let str = "\u22CE" document.write("My symbol: " + str)	My symbol: ⋎
