Modulus Operator

[Amir Abbas Mooman]

sir i want to know about the modulus operater and please tell me how to operator

class Modulus {

public static void main(String [] args){
int a=3;
int b=5;
System.out.println("The ans of b%a "+b%a);//in this ans come 2
System.out.println("The ans of b/a "+ b/a);

System.out.println("The ans of a%b "+a%b);//in this ans come 3 why?
System.out.println("The ans of a/b "+a/b);
}}

The modulus is basically the remainder of dividing two numbers.
To find 5%3 just think of 5/3 which is 1 with a remainder of 2
10%2 is 0 because the two numbers divide evenly with no remainder.
For 3%5 the answer is 3 because 3/5 is 0 with a remainder of 3. I have heard the modulus operator referred to as the remainder operator.

Hi!
Sometimes you will bump into this sort of code.
-5%2
-5%-2
As I've been thought from KHE remeber that if any of the int values �r negative then the product of the modulos results a negative result. If both are negative then it results in a negative result. Therefor, don't pay to much attention to the negative number.
5%2
5-2 = 3
3-2 = 1
1 - 2 1 < 2 so the result is 1
5%2= 1
add a - infront of 1
result = -1.
This is just how you could think. In normal mathematics using -5%-2you must actually add. Like this
-5%2- To reduce the value add
-5+2 = -3
-3+2 = -1
so -5%2= -1
In nagative number mod negative number the actuall calculation goes something like this.
-5%-2- to reduce the value
-5-(-2) = -3
-3-(-2) = -1
result -1
// Hope I didn't mess things up for you
