Why does floor division return a float instead of an int

Question

a = 6
b = 2
c = 9

print(c/b//b)

Could anyone tell why is the result of this 2.0 instead of 2? 9/2 = 4.5 4.5//2 should be 2 bcos floor division rounds it to the nearest integer value. But why is the result 2.0?

Answer 1

The floor division gives round off value. But it necessarily not give an integer. So it depends on the type of operands and as 4.5 is a float value, hence the answer must be a float. And that's why 4//2 = 2 and 4.5//2 = 2.0
