The "Squared Dot Operator" Symbol (⊡)

The ⊡ symbol, commonly referred to as the "Squared Dot Operator," visually appears as a dot centered inside a square. It is used in mathematical contexts for various purposes based on the field or topic of discussion.

## Visual Representation

The ⊡ symbol essentially looks like a small centered dot inside a square. The square frames the dot, emphasizing its significance or differentiating it from other dot-based symbols.

## Usage

The precise usage of the ⊡ can vary depending on the field of mathematics or the specific context in which it is applied. In some contexts, it might be used to represent a specialized operation, and in others, it might be a unique notation to distinguish it from the typical dot product or multiplication symbol.

It's essential to refer to the context or the specific mathematical topic being discussed to understand the exact meaning and application of the ⊡ symbol.

## Typing ⊡

To represent the "Squared Dot Operator" symbol on platforms or documents that recognize HTML entities, you can use the ⊡ entity. Do note that the visual representation might differ slightly based on the font and platform you are using. In non-HTML contexts or other software, you may need to find a specific method or use a dedicated library to depict the symbol accurately.

## Related Symbols

There are several dot-related symbols in mathematics, each having its own significance. Some of these include:

• ⋅ (Dot Operator)
• ċ (Centered Dot Operator)
• ⊙ (Circled Dot Operator)

## Conclusion

The ⊡ symbol, like many mathematical symbols, carries a specific meaning depending on the context it's used in. While it may not be as commonly encountered as other dot operators, it remains a useful notation in specific mathematical niches or areas of study.

## Codes for the ⊡ Symbol

 The Symbol ⊡ Alt Code Alt 8865 HTML Code ⊡ HTML Entity ⊡ CSS Code \22A1 Hex Code ⊡ Unicode U+22A1

## 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 8865. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

(Method 3) Use the HTML Decimal Code (for webpages).

HTML TextOutput
<b>My symbol: &#8865;</b>My symbol: ⊡

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

HTML TextOutput
<b>My symbol: &sdotb;</b>My symbol: ⊡

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

CSS and HTML TextOutput
<style>
span:after {
content: "\22A1";}
</style>
<span>My symbol:</span>
My symbol: ⊡

(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).

HTML TextOutput
<b>My symbol: &#x22A1;</b>My symbol: ⊡
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22A1 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+22A1. 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:
TypeOutput
22A1
[Hold down Alt]
[Press x]

(The 22A1 turns into ⊡. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22A1. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22A1"
document.write("My symbol: " + str)
My symbol: ⊡
