## The Mathematical Symbol "Less-Than But Not Equivalent To (⋦)"

The "Less-Than But Not Equivalent To" Symbol (⋦): Drawing the Line between Similarity and Order

Mathematical notation offers a unique language to capture nuanced relationships with finesse. The ⋦ symbol, denoting "Less-Than But Not Equivalent To", is a compelling illustration of this precision. It encapsulates both an ordinal relationship and a distinction from equivalence. This article aims to demystify this intriguing symbol and its implications.

## Unpacking the ⋦ Symbol

The ⋦ symbol is multifaceted. At its core, it asserts that one entity is less than another. Additionally, it emphasizes that the two entities are not equivalent, even in an approximate sense. In mathematical expressions, if \( a \) and \( b \) are entities, the relation \( a ⋦ b \) conveys that \( a \) is less than \( b \), and they are not approximately equal.

Example 1: Number Comparison

Consider the numbers 3 and 3.001. While they are close in value, in a context where precision is paramount, one could state:

3 ⋦ 3.001

This denotes that 3 is not just less than 3.001, but they are also not deemed equivalent in the given context.

Example 2: Analyzing Functions

Let \( f(x) \) and \( g(x) \) be functions where \( f(x) \) is always slightly below \( g(x) \) but not close enough to be considered equivalent. For such functions, over a certain range of \( x \), one could write:

\( f(x) ⋦ g(x) \) for that range.

## Applications and Importance

The ⋦ symbol's unique blend of order and distinction from approximation finds utility in:

**Real Analysis:**Emphasizing distinctions between real numbers or functions, especially when dealing with limits.**Physics:**When comparing quantities where even minute differences matter, such as in quantum mechanics.**Computer Algorithms:**For algorithms where precision in comparisons is crucial.

Its ability to denote both ordinal difference and non-equivalence ensures that relationships are defined with utmost clarity, making ⋦ an invaluable tool in many mathematical discussions.

In summary, the ⋦ symbol exemplifies the richness of mathematical notation. By capturing a dual essence of order and distinction, it facilitates precise articulation of relationships, ensuring clarity in analysis and reasoning.

## Codes for the ⋦ Symbol

The Symbol | ⋦ | |

Alt Code | Alt 8934 | |

HTML Code | ⋦ | |

HTML Entity | ⋦ | |

CSS Code | \22E6 | |

Hex Code | ⋦ | |

Unicode | U+22E6 |

## 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 8934. 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: ⋦</b> | My symbol: ⋦ |

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

HTML Text | Output |
---|---|

<b>My symbol: ⋦</b> | My symbol: ⋦ |

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

CSS and HTML Text | Output |
---|---|

<style> span:after { content: "\22E6";} </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: ⋦</b> | My symbol: ⋦ |

**0x22E6**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+22E6**. 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 |
---|---|

22E6 [Hold down Alt] [Press x] | ⋦ (The 22E6 turns into ⋦. Note that you can omit any leading zeros.) |

JavaScript Text | Output |
---|---|

let str = "\u22E6" document.write("My symbol: " + str) | My symbol: ⋦ |
