# Introduction In mathematics, the **floor()** function is used to calculate the largest integer that is less than or equal to a given number. In Python, this function is implemented in the Numpy library as **numpy.floor()**. It is used to return the floor value of the elements of an array. In this lab, you will learn how to use **numpy.floor()** function to calculate the floor value of an array. ## VM Tips After the VM startup is done, click the top left corner to switch to the **Notebook** tab to access Jupyter Notebook for practice. Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook. If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
