The Mathematical Symbol "Neither Greater-Than nor Equivalent To (≵)"

Diving into the "Neither Greater-Than nor Equivalent To" Symbol (≵)

Mathematics thrives on precision, with symbols playing a vital role in succinctly conveying complex relations. The ≵ symbol, denoting "Neither Greater-Than nor Equivalent To," is one such tool that provides clarity in comparative operations. This article aims to explore its usage and implications in mathematical contexts.

Interpreting ≵

The ≵ symbol is used to assert that one number is neither greater than nor roughly equivalent to another. In contexts where approximation or similarity is being discussed, this symbol helps in asserting that not only is one value not greater than the other, but it's also not approximately equal to it.

Example 1: Numeric Comparison

If we have two real numbers, x and y, the assertion \( x ≵ y \) indicates that x is neither greater than y nor is it approximately equal to y.

Example 2: Estimations

Consider an instance where scientists are comparing measurements from two experiments. If one result is denoted as A and another as B, stating \( A ≵ B \) underscores that not only is A not greater than B, but the results aren't even in the same ballpark of estimation.

Fields of ≵ Application

The ≵ symbol can be seen in diverse mathematical and scientific disciplines:

  • Analysis: For discussing limits or approximations.
  • Statistics: When comparing data sets or specific data points.
  • Engineering: In scenarios where tolerances and approximations are essential to design or analysis.

Its role is crucial for instances where there's a need to highlight distinctions not only in magnitude but also in approximation levels.

To conclude, the ≵ symbol, encapsulating "Neither Greater-Than nor Equivalent To", is invaluable for mathematical and scientific discourses requiring a fine-tuned level of comparison. It emphasizes the robust vocabulary that mathematical notation offers, allowing for nuanced discussions and analyses.

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 8821. 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: &#8821;</b>My symbol: ≵

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

HTML TextOutput
<b>My symbol: &ngsim;</b>My symbol: ≵

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

CSS and HTML TextOutput
span:after {
content: "\2275";}
<span>My symbol:</span>
My symbol: ≵

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

HTML TextOutput
<b>My symbol: &#x2275;</b>My symbol: ≵
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2275 to place the ≵ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"E9"
ctx.fillText(String.fromCodePoint(x), 5, 5);

(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).

The Unicode for ≵ is U+2275. 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:
[Hold down Alt]
[Press x]

(The 2275 turns into ≵. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u2275. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u2275"
document.write("My symbol: " + str)
My symbol: ≵
