Mathematically, the floor function is denoted by the floor ⌊x⌋ symbol and the floor (x). The shape of the floor symbol looks like a square bracket ⌊x⌋ with no tops. From programming to mathematics, the floor symbol plays a vital role in showing a specific function.
Many users add the floor function while creating the technical document in any document processor. However, a floor function requires the correct use of the source code to create it. If you want to learn how to write and use a floor symbol in LaTeX, this tutorial is for you. Let’s get started!
How to Write and Use a Floor Symbol in LaTeX
To write a floor symbol in LaTeX, you must use the $\floor$ as a source code. For example, you can create an expression with a floor function using the following source code:
\usepackage{amssymb}
\begin{document}
$$\lfloor X \rfloor$$
\end{document}
Output:
As you can see in the previous source code, the \rfloor is used for the right side floor symbol while the \lfloor is used for the left side. Similarly, you can create different types of equations that include the floor symbol:
\usepackage{amssymb}
\begin{document}
$\lfloor x+n \rfloor$ = $\lfloor x \rfloor$ + $n$;
$\lfloor -x \rfloor$ = $\lfloor \frac{1}{x+n} \rfloor$ + $n$
$\lfloor \frac{1}{x} \rfloor$ = $\lfloor{\lfloor x \rfloor}\rfloor$ + $n$
\end{document}
Output:
In case you want to create a large floor symbol, use the following source code:
\usepackage{amssymb}
\begin{document}
$\bigg \lfloor \bigg \lfloor \bigg \lfloor x+n \bigg \rfloor \bigg \rfloor \bigg \rfloor $
\end{document}
Output:
Conclusion
This is a brief information about the floor symbol in LaTeX. A floor function is a part of mathematics denoted by ⌊x⌋, where x is a real number. That’s why LaTeX contains a specific source code to write this symbol quickly. LaTeX is full of symbols. If you want to know more, visit our official website.
