# Decimal Narrowing Conversion (Decimal to Int32)

Visual Studio 2010

Converts a Decimal to a 32-bit signed integer.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

## Syntax

```'Declaration
Public Shared Narrowing Operator CType ( _
value As Decimal _
) As Integer
```

#### Parameters

value
Type: System.Decimal
The value to convert.

#### Return Value

Type: System.Int32
A 32-bit signed integer that represents the converted Decimal.

## Exceptions

ExceptionCondition
OverflowException

value is less than Int32.MinValue or greater than Int32.MaxValue.

## Remarks

This operator supports the explicit conversion of a Decimal to a Int32. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to an Int32 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToInt32 or the Convert.ToInt32(Decimal) method.

## Examples

The following code example converts Decimal numbers to Int32 values using the explicit Decimal to Int32 conversion.

```
' Example of the explicit conversions from Decimal to Integer and
' Decimal to UInteger.
Module DecimalToU_Int32Demo

Const formatter As String = "{0,17}{1,19}{2,19}"

' Convert the decimal argument catch exceptions that are thrown.
Public Sub DecimalToU_Int32(argument As Decimal)
Dim Int32Value As Object
Dim UInt32Value As Object

' Convert the argument to an int value.
Try
Int32Value = CInt(argument)
Catch ex As Exception
Int32Value = ex.GetType().Name
End Try

' Convert the argument to a uint value.
Try
UInt32Value = CUInt(argument)
Catch ex As Exception
UInt32Value = ex.GetType().Name
End Try

Console.WriteLine(formatter, argument, _
Int32Value, UInt32Value)
End Sub

Public Sub Main( )
Console.WriteLine( formatter, "Decimal Argument", _
"Integer/Exception", "UInteger/Exception" )
Console.WriteLine( formatter, "----------------", _
"-------------", "--------------" )

' Convert decimal values and display the results.
DecimalToU_Int32( 123d)
DecimalToU_Int32(New Decimal(123000, 0, 0, False, 3))
DecimalToU_Int32(123.999d)
DecimalToU_Int32(4294967295.999d)
DecimalToU_Int32(4294967296d)
DecimalToU_Int32(2147483647.999d)
DecimalToU_Int32(2147483648d)
DecimalToU_Int32(-0.999d)
DecimalToU_Int32(-1d)
DecimalToU_Int32(-2147483648.999d)
DecimalToU_Int32(-2147483649d)
End Sub
End Module
' The example displays the following output to the console:
