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

Parameters

value
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.

Exception Condition
OverflowException

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
         Try
            Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value))
         Catch e As OverflowException
            Console.WriteLine("Unable to calculate the absolute value of {0}.", _
                              value)
         End Try   
      Next
   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.
