Floor symbol ⌊..⌋ in LaTeX

Symbol/Unicode Floor
Type of symbol Mathematics
Package (requirement) No
Argument Yes
Latex command \lfloor arg \rfloor
Example \lfloor arg \rfloor → ⌊arg⌋

You need to use the \lfloor arg \rfloor command to print the floor symbol in a latex document. But if the equation is large, I would recommend using the \left\lfloor arg \right\rfloor command. By this, the size of the symbol will be automatically adjusted as the size of the equation.

\documentclass{article}
\begin{document}
$$\lfloor a, b \rfloor$$
$$\left\lfloor \frac{2m+x}{n} \right\rfloor$$
$$\left\lfloor \frac{(n-1)m+x}{n} \right\rfloor$$
\end{document}

Output :
