# Decimal Explicit Conversion (Decimal to Int32)

.NET Framework 4.5

Defines an explicit conversion of a Decimal to a 32-bit signed integer.

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

## Syntax

```public static explicit operator int (
decimal value
)
```

#### 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 example converts Decimal numbers to Int32 values by using the explicit Decimal to Int32 conversion.

```// Example of the explicit conversions from decimal to int and
// decimal to uint.
using System;

class DecimalToU_Int32Demo
{
const string formatter = "{0,17}{1,19}{2,19}";

// Get the exception type name; remove the namespace prefix.
public static string GetExceptionType( Exception ex )
{
string exceptionType = ex.GetType( ).ToString( );
return exceptionType.Substring(
exceptionType.LastIndexOf( '.' ) + 1 );
}

// Convert the decimal argument; catch exceptions that are thrown.
public static void DecimalToU_Int32( decimal argument )
{
object Int32Value;
object UInt32Value;

// Convert the argument to an int value.
try
{
Int32Value = (int)argument;
}
catch( Exception ex )
{
Int32Value = GetExceptionType( ex );
}

// Convert the argument to a uint value.
try
{
UInt32Value = (uint)argument;
}
catch( Exception ex )
{
UInt32Value = GetExceptionType( ex );
}

Console.WriteLine( formatter, argument,
Int32Value, UInt32Value );
}

public static void Main( )
{
Console.WriteLine(
"This example of the explicit conversions from decimal " +
"to int \nand decimal to uint generates the following " +
"output. It displays \nseveral converted decimal " +
"values.\n" );
Console.WriteLine( formatter, "decimal argument",
"int/exception", "uint/exception" );
Console.WriteLine( formatter, "----------------",
"-------------", "--------------" );

// Convert decimal values and display the results.
DecimalToU_Int32( 123M );
DecimalToU_Int32( new decimal( 123000, 0, 0, false, 3 ) );
DecimalToU_Int32( 123.999M );
DecimalToU_Int32( 4294967295.999M );
DecimalToU_Int32( 4294967296M );
DecimalToU_Int32( 2147483647.999M );
DecimalToU_Int32( 2147483648M );
DecimalToU_Int32( - 0.999M );
DecimalToU_Int32( - 1M );
DecimalToU_Int32( - 2147483648.999M );
DecimalToU_Int32( - 2147483649M );
}
}
