'Declaration
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.

ExceptionCondition
OverflowException

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

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

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
