## The Mathematical Symbol "Neither Approximately nor Actually Equal To (≇)"

Deciphering the "Neither Approximately nor Actually Equal To" Symbol (≇)

In the vast realm of mathematical notation, each symbol serves as a shorthand, enabling concise representation of intricate relations and concepts. The ≇ symbol, which denotes "Neither Approximately nor Actually Equal To", is a perfect example. In this article, we'll explore its usage and the depth it brings to mathematical expressions.

## Breaking Down ≇

The ≇ symbol is employed to convey a specific relationship between two mathematical entities. It asserts that not only are these entities not exactly equal, but they are also not even approximately equal. This distinction emphasizes a clear difference between the two subjects of comparison.

Example 1: Comparing Real Numbers

For two real numbers, say x and y, the statement \( x ≇ y \) conveys that x is neither exactly equal to nor approximately equivalent to y.

Example 2: Geometry Context

When comparing the areas of two geometric shapes, A and B, if one were to say \( A ≇ B \), it indicates that not only are the areas of A and B different, but they are also not nearly the same.

## Fields of ≇ Application

The ≇ symbol finds its place in various areas of mathematics and its applications:

**Geometry:**For comparing lengths, angles, and areas.**Analysis:**Especially in contexts where approximation is discussed.**Algebra:**In the study of algebraic structures and their properties.

By using this symbol, mathematicians can effectively differentiate between exact equivalences and close approximations, adding another layer of precision to their discussions.

In summary, the ≇ symbol, representing "Neither Approximately nor Actually Equal To", offers an invaluable tool for distinguishing and comparing mathematical entities. Its existence showcases the richness and nuance of mathematical notation, catering to diverse analytical needs.

## Codes for the ≇ Symbol

The Symbol | ≇ | |

Alt Code | Alt 8775 | |

HTML Code | ≇ | |

HTML Entity | ≇ | |

CSS Code | \2247 | |

Hex Code | ≇ | |

Unicode | U+2247 |

## 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 8775. 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: "\2247";} </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: ≇ |

**0x2247**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+2247**. 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 |
---|---|

2247 [Hold down Alt] [Press x] | ≇ (The 2247 turns into ≇. Note that you can omit any leading zeros.) |

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

let str = "\u2247" document.write("My symbol: " + str) | My symbol: ≇ |
