round down using round( in python

You can use the math.floor() function to round down a number to the nearest integer. To use it with the round() function, you can provide the number to be rounded down as the first argument and the number of decimal places to round to as the second argument, and then pass the result to math.floor(). Here's an example:

main.py
import math

x = 3.14159
rounded_down = math.floor(round(x, 2))

print(rounded_down) # Output: 3

7 lines

In this example, the round() function first rounds x to two decimal places (giving 3.14), and then math.floor() rounds down the result to the nearest integer (3).
