% Operator (C# Reference)

Visual Studio 2005

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

Remarks

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.

Example

// 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
