What does the modulus operator do?

Question

english is not my native language, i understand almost everything, but not the modulus. Help!!!

Answer 1

its like 12%5=2 because 5*2= 10, then it will rest 2, and this is the answer, 12%5=2 right?!

Answer 2

thanks, you just teach me a new operator :P

Answer 3

It's a strange operator :
It returns the rest of a division :
12%5=2 // weird uh ?
2*5=10
12-10=2

another exemple :
5%2=1
2*2=4
5-4=1

Ask if you don't understand !

Answer 4

why the another example, it is 2*2 and not 2*1?

Answer 5

5%2 --> 5/2 how much 2 in 5, two because
2*2=4 4<5and 2*3=6. 6>5 2 is the 'quotient' (sorry I'm french X) )
Then to find the rest : 5-4=1

I don't know if it's ok, it's difficult to explain
If you still don't understand, I can try a code

Answer 6

ohhh now i completely understand, thanks a lot ^-^

Answer 7

Exactly !!
