Floor division is a mathematical operation that rounds down the result of a division operation to the nearest integer. It is represented by two forward slashes (//) in Python. The floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor(x). For example, if we have two variables x and y, and we want to perform floor division on them, we can simply use the // operator as shown in the code given below:

x = 5
y = 2
print(x//y)

The output of the above code will be 2, which is the result of the floor division operation. When we perform floor division on operands of different types, Python automatically converts them to a common type before performing the division operation. For example, if we divide an integer by a float using floor division, the integer is automatically converted to a float before the division operation is performed.
