SUMMARY

The discussion centers on the floor function, denoted as $$\lfloor x \rfloor$$, which represents the largest integer not greater than a given real number $x$. This function is crucial in various mathematical applications and is defined by the set equation $$\lfloor x \rfloor=\max\{m\in\mathbb{Z}\,|\,m\le x\}$$. Understanding the floor function is essential for grasping concepts related to integer parts and rounding in mathematics.

That is one way to denote the floor function, more commonly given as $$\lfloor x \rfloor$$, which means the largest integer not greater than $x$. Its value at $x$ is called the integral part or integer part of $x$. The fllor function may be defined by the set equation:

$$\lfloor x \rfloor=\max\{m\in\mathbb{Z}\,|\,m\le x\}$$
