d As Decimal _
) As Integer
```

#### Parameters

## 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
