$\sqbrk x$

For $x \in \R$, the greatest integer less than or equal to $x$.

That is, it is the integer part of a given real number.

$\sqbrk x$ has been (or is in the process of being) superseded by $\floor x$, due to the already widespread uses of square brackets.

The $\LaTeX$ code for $\sqbrk x$ is \sqbrk x .
