Hey , I really want to know what the modulus operator is, because I tried to understand this months before , and after hours I still dont' know

I googled and it says the modulus operator returns the remainder of division of a number by another one.

but I don't get it , I tried alot in C++

Code:
    int a=2,b=3,c;
    c= a%b;


it returns 2

but how ? 2 /3 = 0.6666 or 1

when I assigned 100 to a it returned 1

again I don't understand , 100/3 = 33

EDIT : Never mind I GET IT Smile

100/3 = 33
33*3 =99
100-99 =1

something like that Very Happy

When two is divided by three, three cannot go into two even once. Therefore, the remainder is two.

@OP it rounds up, 100 / 3 is 33.3333333333333333 the .33333333333333 rounded to 1 is the modulous of 100 / 3.

100 % 6 = 4

Doesn't it round down ?

100/3 = 33.3333333
34*3 = 102

you had it correct in the first posts. Modulus is what is left after being divided by the given value

Modulus is not simply rounding the decimal portion of the quotient up, consider:

200 / 3 = 66.66666666666
Remainder is 0.6666666666, rounded up is 1
200 - 1 = 199
199 / 3 = 66.33333333333, which is incorrect

Modulus is truncated rounding of the quotient and returning the remainder:
200 / 3 = 66.66666666666
Truncating the quotient, you get 66.
200 - (3 * 66) = 2
200 - 2 = 198
198 / 3 = 66, which is correct
