## The Mathematical Symbol "Estimates (≙)"

The ≙ Symbol in Mathematics: Estimates

Mathematics offers a rich tapestry of symbols, each carrying its own nuanced meaning. Among these symbols, the ≙ symbol, labeled as "Estimates", is of special interest.

## Usage

The ≙ symbol is commonly used to express an approximation or an estimation of equivalence between two values or entities. It signifies that while two quantities might not be precisely equal, one provides a reasonable estimation or approximation of the other.

## Examples

**Example 1:**When comparing an approximate value of a variable \( x \) to a known value \( y \), one might express:

\( x ≙ y \)

This suggests that "x estimates y" or "x is roughly equivalent to y".**Example 2:**In statistical contexts, when a model's predicted value \( p \) is close to the observed value \( o \), it can be conveyed as:

\( p ≙ o \)

Indicating that the model's prediction is a good estimation of the observed value.

To encapsulate, the ≙ symbol provides a concise notation to represent approximations or estimations in mathematical expressions. It conveys a sense of near equivalence or a close estimate between two quantities, making it pivotal in contexts where precision isn't strictly demanded.

## Codes for the ≙ Symbol

The Symbol | ≙ | |

Alt Code | Alt 8793 | |

HTML Code | ≙ | |

HTML Entity | ≙ | |

CSS Code | \2259 | |

Hex Code | ≙ | |

Unicode | U+2259 |

## 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 8793. 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: "\2259";} </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: ≙ |

**0x2259**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+2259**. 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 |
---|---|

2259 [Hold down Alt] [Press x] | ≙ (The 2259 turns into ≙. Note that you can omit any leading zeros.) |

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

let str = "\u2259" document.write("My symbol: " + str) | My symbol: ≙ |
