Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function Abs (
	value As SByte
) As SByte


Type: System.SByte

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

Return Value

Type: System.SByte

An 8-bit signed integer, x, such that 0 x SByte.MaxValue.

Exception Condition

value equals SByte.MinValue.

The absolute value of a signed byte is its numeric value without its sign. For example, the absolute value of both 12 and -12 is 12.

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

Module Example
   Public Sub Main()
      Dim values() As SByte = { SByte.MaxValue, 98, 0, -32, SByte.MinValue }
      For Each value As SByte 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(127) = 127
'       Abs(98) = 98
'       Abs(0) = 0
'       Abs(-32) = 32
'       Unable to calculate the absolute value of -128.
