How to Round Float Values to Ints in Python DataFrames Using Pandas

Data manipulation is a vital skill when working with datasets in Python, particularly when using libraries like Pandas and NumPy. One common task you may encounter is the need to round float values to integers within a DataFrame. This guide will help you understand how to perform this operation efficiently, using a clear example.

The Problem: Rounding Floats to Ints

Imagine you have a DataFrame called df, which contains various float values. You want to convert these floats to integers, specifically ensuring that none of the values are rounded down incorrectly. Here's a snapshot of what your DataFrame looks like:
