The '\ulcorner' is a Tex command used to display a left-hand corner symbol with an underline. This can be used in mathematical equations or as a decorative element in a document.

Syntax

\ulcorner

Example

\begin{equation}
f(x)=\begin{cases} 
      x^2-1 & \ulcorner x\urcorner<1 \\
      \cos(\pi x) & \ulcorner x\urcorner\geq1 
   \end{cases}
\end{equation}

Output

The above example will output the following equation:

\begin{equation} f(x)=\begin{cases} x^2-1 & \ulcorner x\urcorner<1 \ \cos(\pi x) & \ulcorner x\urcorner\geq1 \end{cases} \end{equation}

In the above equation, the '\ulcorner' command is used to represent the floor function.
