# Decimal.ToInt32 Method (Decimal)

.NET Framework (current version)

Converts the value of the specified Decimal to the equivalent 32-bit signed integer.

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

## Syntax

```Public Shared Function ToInt32 (
d As Decimal
) As Integer
```

#### Parameters

d
Type: System.Decimal

The decimal number to convert.

#### Return Value

Type: System.Int32

A 32-bit signed integer equivalent to the value of d.

## Exceptions

Exception Condition
OverflowException

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

## Remarks

The return value is the integral part of the decimal value; fractional digits are truncated.

You can also convert a Decimal value to a 32-bit integer by using the Narrowing(Decimal to Int32) assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.

## Examples

The following example uses the ToInt32 method to convert decimal numbers to Int32 values.

```Module Example
Public Sub Main()
Dim values() As Decimal = { 123d, New Decimal(123000, 0, 0, false, 3),
123.999d, 4294967295.999d, 4294967296d,
4294967296d, 2147483647.999d, 2147483648d,
-0.999d, -1d, -2147483648.999d, -2147483649d }

For Each value In values
Try
Dim number As Integer = Decimal.ToInt32(value)
Console.WriteLine("{0} --> {1}", value, number)
Catch e As OverflowException
Console.WriteLine("{0}: {1}", e.GetType().Name, value)
End Try
Next
End Sub
End Module
' The example displays the following output:
'       123 --> 123
'       123.000 --> 123
'       123.999 --> 123
'       OverflowException: 4294967295.999
'       OverflowException: 4294967296
'       OverflowException: 4294967296
'       2147483647.999 --> 2147483647
'       OverflowException: 2147483648
'       -0.999 --> 0
'       -1 --> -1
'       -2147483648.999 --> -2147483648
'       OverflowException: -2147483649
'
```
