# How to Write Approximately Equal (≈) Symbol in LaTeX

**To Write approximate symbol in LaTeX document, use the LaTeX command \approx . It will add ≈ symbol in the text. The Approximately equal symbol (≈) holds a significant importance as it represents the approximation or similarity between two values.**

In this article, we will discuss how to type approximately symbol (≈) in LaTeX document and its practical applications while working on mathematical equations, scientific papers or technical documents.

## Symbol Overview

**Symbol:** Approximately Equal

**Unicode:** U+2248

**Type:** Mathematical

**Package Requirement:** None (built-in symbol)

**Argument:** None (no additional arguments needed)

**LaTeX Command:** \approx

**Example:** ≈

## Syntax

To insert the approximately equal symbol (≈) in LaTeX, you will need to use the backslash followed by the “approx” command.

```
\approx
```

## Examples of using the Approximate Equal Symbol

Let’s explore some of the practical examples of using the LaTeX command to write the approximately equal symbol.

### Denote “X is approximately equal to y”

```
\documentclass{article}
\begin{document}
X \approx y
\end{document}
```

Output: 👇️

X ≈ y

In the above example, the approximately symbol is represented by two similar to symbol and express the similarity in two values.

### Use Approximately Equal Symbol in Mathematical Expression

```
\documentclass{article}
\begin{document}
10\% \approx 0.1
\end{document}
```

Output: 👇️

10% ≈ 0.1

Here, in this example, the approximately symbol is used in the mathematical expression to display similarity in the two values such as 10% is similar to 0.1 value.

### Using the amssymb Package to use Approximately Equal Symbol

You can use LaTeX command `\thickapprox `

from the package `amssymb`

to write the approximately symbol (≈) in LaTeX document.

```
\documentclass{article}
\usepackage{amssymb}
\begin{document}
\[ x \thickapprox y \]
\end{document}
```

Output: 👇️

x ≈ y

Here, in this example, we have use package `amssymb`

that provides `\thickapprox`

command to write approximately symbol (≈) in the LaTeX documents.

## Use of Approximately Equal Symbol in Mathematical Equations

The approximately equal symbol (≈) is commonly used in mathematical equations to represent approximation, rounding, or similarity betweeen values.

It is used in statistics, numerical analysis, and physics to signify an acceptable degree of precision.

## Conclusion

Using the LaTeX command `\approx`

, you can write the approximately equal symbol (≈) in LaTeX documents. The approximately equal symbol (≈) is used to express approximations or similarities between values.

While using the approximate equal symbol in LaTeX document, ensure appropriate spacing around the symbol in mathematical expressions for better readability.
