Floor division and modulo operator?

Question

Can i ask? what is floor division("//") and modulo operator ("%")? I still don't get it. In my school there is no lesson with it, so can anyone explain it to me. Thank you in advance!

Answer 1

This doesn't tell the whole story, but maybe it's a good starting point (as long as numbers don't get negative):

Q: How often does the 6 fit into the 20?

A: 3 times! //

Q: But what will be left after that?

A: 2! %

Answer 2

Modulo operator gaves you the remainder of the division of those numbers: Ex
5 / 3 returns 2, as 5 over 3 is 1 with a remainder of 2.

Floor division gaves you a integrer result, no matter the result is a float or the numbers used are float or not.
EX:
5/2 -> 2.5
5//2 -> 2

Answer 3

Making a division m/n it's just like making"packs" of n elements of a total of m elements. Imagine you have 10 apples, and you want yo make packs of 3 apples. How many packs can you make? 3 full packs. However, there is one apple left, and you can not make a full pack with just one apple. The modulo is the number of items left, which are not enough to make a full pack. In this case, as we have one apple left, we have a modulo of 1

10 / 3 gaves you a remainder (modulo) of 1. Written in Python,
a = 10%3. In this case, the variable a holds the value 1.

Answer 4

I still don't get it? the mudolo operator

Answer 5

so, in floor the division it is just like a division but it always gives you an integer answer? so my i ask why is 20//6 = 3? right?
