Math.Abs Method (Int32)

Returns the absolute value of a 32-bit signed integer.

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

Public Shared Function Abs ( _
	value As Integer _
) As Integer


Type: System.Int32

A number that is greater than Int32.MinValue, but less than or equal to Int32.MaxValue.

Return Value

Type: System.Int32
A 32-bit signed integer, x, such that 0 x Int32.MaxValue.


value equals Int32.MinValue.

The absolute value of an Int32 is its numeric value without its sign. For example, the absolute value of both 123 and -123 is 123.

The following example uses the Abs(Int32) method to get the absolute value of a number of Int32 values.

Module Example
   Public Sub Main()
      Dim values() As Integer = { Int32.MaxValue, 16921, 0, -804128, Int32.MinValue }
      For Each value As Integer In values
            Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value))
         Catch e As OverflowException
            Console.WriteLine("Unable to calculate the absolute value of {0}.", _
         End Try    
   End Sub 
End Module 
' The example displays the following output: 
'       Abs(2147483647) = 2147483647 
'       Abs(16921) = 16921 
'       Abs(0) = 0 
'       Abs(-804128) = 804128 
'       Unable to calculate the absolute value of -2147483648.
