# DivideByZeroException Class

## Definition

The exception that is thrown when there is an attempt to divide an integral or Decimal value by zero.

## Examples

The following example handles a DivideByZeroException exception in integer division.

``````using System;

public class Example
{
public static void Main()
{
int number1 = 3000;
int number2 = 0;
try {
Console.WriteLine(number1 / number2);
}
catch (DivideByZeroException) {
Console.WriteLine("Division of {0} by zero.", number1);
}
}
}
// The example displays the following output:
//        Division of 3000 by zero.
``````
``````open System

let number1 = 3000
let number2 = 0
try
printfn \$"{number1 / number2}"
with :? DivideByZeroException ->
printfn \$"Division of {number1} by zero."

// The example displays the following output:
//        Division of 3000 by zero.
``````
``````Module Example
Public Sub Main()
Dim number1 As Integer = 3000
Dim number2 As Integer = 0
Try
Console.WriteLine(number1\number2)
Catch e As DivideByZeroException
Console.WriteLine("Division of {0} by zero.", number1)
End Try
End Sub
End Module
' The example displays the following output:
'       Division of 3000 by zero.
``````

## Remarks

Trying to divide an integer or Decimal number by zero throws a DivideByZeroException exception. To prevent the exception, ensure that the denominator in a division operation with integer or Decimal values is non-zero.

Dividing a floating-point value by zero doesn't throw an exception; it results in positive infinity, negative infinity, or not a number (NaN), according to the rules of IEEE 754 arithmetic. Because the following example uses floating-point division rather than integer division, the operation does not throw a DivideByZeroException exception.

``````using System;

public class Example
{
public static void Main()
{
int number1 = 3000;
int number2 = 0;

Console.WriteLine((double)number1 / number2);
}
}
// The example displays the following output:
//        Infinity
``````
``````open System

let number1 = 3000.
let number2 = 0.

printfn \$"{number1 / number2}"

// The example displays the following output:
//        Infinity
``````
``````Module Example
Public Sub Main()
Dim number1 As Integer = 3000
Dim number2 As Integer = 0

Console.WriteLine(number1/number2)
End Sub
End Module
' The example displays the following output:
'       Infinity
``````

The following Microsoft intermediate language (MSIL) instructions throw DivideByZeroException:

• div

• div.un

• rem

• rem.un

DivideByZeroException uses the HRESULT COR_E_DIVIDEBYZERO, which has the value 0x80020012.

For a list of initial property values for an instance of DivideByZeroException, see the DivideByZeroException constructors.

## Constructors

 Initializes a new instance of the DivideByZeroException class. Initializes a new instance of the DivideByZeroException class with serialized data. Initializes a new instance of the DivideByZeroException class with a specified error message. Initializes a new instance of the DivideByZeroException class with a specified error message and a reference to the inner exception that is the cause of this exception.

## Properties

 Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception) Gets or sets a link to the help file associated with this exception. (Inherited from Exception) Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception) Gets the Exception instance that caused the current exception. (Inherited from Exception) Gets a message that describes the current exception. (Inherited from Exception) Gets or sets the name of the application or the object that causes the error. (Inherited from Exception) Gets a string representation of the immediate frames on the call stack. (Inherited from Exception) Gets the method that throws the current exception. (Inherited from Exception)

## Methods

 Determines whether the specified object is equal to the current object. (Inherited from Object) When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception) Serves as the default hash function. (Inherited from Object) When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception) Gets the runtime type of the current instance. (Inherited from Exception) Creates a shallow copy of the current Object. (Inherited from Object) Creates and returns a string representation of the current exception. (Inherited from Exception)

## Events

 Obsolete. Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception)
