C# modulus operator [closed]

Answer 1

As explained by others, but if you don't want to use the "mod" operator. Here is the equation to figure out the remainder of "a" divided by "n"

a-(n* int(a/n))

Answer 2

Another "as explained by others", but if you're curious about several more ways to do modulus (or use an alternative method), you can read this article which benchmarks a few different ways.

Basically, the fastest way is the good old fashioned modulus operator, similar to:

if (x % threshold == some_value)
{
    //do whatever you need to
}

Answer 3

I already think that the user may have understood the answers. Because there are so many good programmer.. in simple wording % tells you the reminder after dividing with your own integer.

e.g.

int a = int.Parse(Console.ReadLine());
int b = a % 2;

Now your input 13, it will give 1, because after diving 13 by 2 remainder is 1 in simple mathematics. Hope you got that.

Answer 4

Because the remainder of 3 / 4 = 3.

Answer 5

I wasn't quite sure what to expect, but I couldn't figure out how the remainder was 3.

So you have 3 cookies, and you want to divide them equally between 4 people.

Because there are more people than cookies, nobody gets a cookie (quotient = 0) and you've got a remainder of 3 cookies for yourself. :)

Answer 6

3 mod 4 is the remainder when 3 is divided by 4.

In this case, 4 goes into 3 zero times with a remainder of 3.
