Math.Abs Method (Int32)

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

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

'Declaration
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.

ExceptionCondition
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.


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
' 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.
