Python Problem III

Question

I just discovered another something:

Why do you think print(-22 // 10) return -3?

Can someone explain this code?
Thanks for any response that you make.

Answer 1

Just like 『 AVD-01 』 said. "//" Is a floor division operator. Which divides the numbers and return the *floor* of the result.
Which is number less than or equal to the answer.
In this case -22/10 = -2.2
And floor(-2.2) = -3

And not -2 as (-2 > -2.2)

Answer 2

22 // 10 #2 <= 2.2
-22 // 10 #-3 <= (-2.2)

-22 // 11 #2 <= 2

Answer 3

It is called floor division, done using // operator

When floor dividing, the result of normal division is round off to nearest whole number

-22//11 returns -2 as its the nearest whole number, and it never returns -3 I guess
