How to Write Ceiling Brackets (⌈ ⌉) in LaTeX

In LaTeX, you can write ceiling brackets using the \lceil and \rceil commands.

The following examples show how to write ceiling brackets in LaTeX.

How to Write Ceiling Brackets in Text

For text, we can use the standard keyboard characters, but for proper mathematical formatting, we can use the \lceil and \rceil commands.

Example: Ceiling Brackets in Text

Suppose we want to write ceiling brackets in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

This is an example of using ceiling brackets \(\lceil x \rceil\) in a sentence.

\end{document}

Output: 👇️

This is an example of using ceiling brackets ⌈x⌉ in a sentence.

In this example, we use the ceiling brackets to enclose a variable in the text.

How to Write Ceiling Brackets in Mathematical Expressions

For mathematical expressions, we can use the \lceil and \rceil commands to ensure proper formatting.

Example: Ceiling Brackets in Mathematical Expressions

Suppose we would like to write mathematical expressions that contain ceiling brackets.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( \lceil a + b \rceil \).

A displayed mathematical expression:
\[
\left\lceil \frac{a}{b} \right\rceil + \left\lceil \frac{c}{d} \right\rceil
\]

\end{document}

Output: 👇️

In this example, we use the \lceil and \rceil commands to enclose elements in a ceiling function. The \left\lceil and \right\rceil commands are used to adjust the size of the ceiling brackets to fit the enclosed fractions.

Conclusion

We can use the \lceil and \rceil commands for both text and mathematical expressions.

For larger expressions, the \left\lceil and \right\rceil commands help in adjusting the size of the ceiling brackets automatically.
