These are the two ways the number can be rounded down in Python. It will return inappropriate results if the user passes an invalid number in the parameter. If the numerator is N and the denominator D, then this equation N = D * ( N // D) + (N % D) is always satisfied. The ceil()function will return the mathematical ceiling value i.e. 3 Ways to Find the Length of a Python List, Python Matrix Multiplication in Three Different Ways. To put it another way, the floor of a number is the number rounded down to its nearest integer value. The floor() function gives us the rounded value of each item. Inbuilt round() function in Python: In Python, we are provided with a built-in ... // is the floor division operator of Python.
