# % 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```

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