% Operator (C# Reference)

The modulus operator (%) computes the remainder after dividing its first operand by its second. All numeric types have predefined modulus operators.

User-defined types can overload the % operator (see operator). When a binary operator is overloaded, the corresponding assignment operator, if any, is also implicitly overloaded.

// cs_operator_modulus.cs
using System;
class MainClass
{
    static void Main() 
    {
        Console.WriteLine(5 % 2);       // int
        Console.WriteLine(-5 % 2);      // int
        Console.WriteLine(5.0 % 2.2);   // double
        Console.WriteLine(5.0m % 2.2m); // decimal
        Console.WriteLine(-5.2 % 2.0);  // double
    }
}

Output

 
1
-1
0.6
0.6
-1.2

Note the round-off errors associated with the double type.
