Answer 1

See, flooring -2.5 to the next algebraic number that is lower gives -3, but not -2

Answer 2

floor division ( // ) always rounds down, not towards 0 but down. so -32.5 == -33
32.5 == 33

Answer 3

floor division is always round down. For example 10//3 = 3 but in normal division you will get exact decimals like this 10/3 = 3.3333
