Math.Abs Method (Int16)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Updated: September 2010

Returns the absolute value of a 16-bit signed integer.

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

Syntax

'Declaration
Public Shared Function Abs ( _
    value As Short _
) As Short

public static short Abs(
    short value
)

Parameters

Return Value

Type: System.Int16
A 16-bit signed integer, x, such that 0 ≤ x ≤Int16.MaxValue.

Exceptions

Exception Condition
OverflowException

value equals Int16.MinValue.

Remarks

The absolute value of an Int16 is its numeric value without its sign. For example, the absolute value of both 123 and -123 is 123.

Examples

The following example uses the Math.Abs(Int16) method to get the absolute value of several Int16 values.

Dim values() As Short = {Int16.MaxValue, 10328, 0, -1476, Int16.MinValue}
For Each value As Short In values
   Try
      outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) & vbCrLf
   Catch e As OverflowException
      outputBlock.Text += String.Format("Unable to calculate the absolute value of {0}.", _
                        value) & vbCrLf
   End Try
Next
' The example displays the following output:
'       Abs(32767) = 32767
'       Abs(10328) = 10328
'       Abs(0) = 0
'       Abs(-1476) = 1476
'       Unable to calculate the absolute value of -32768.

short[] values = { Int16.MaxValue, 10328, 0, -1476, Int16.MinValue };
foreach (short value in values)
{
   try
   {
      outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) + "\n";
   }
   catch (OverflowException)
   {
      outputBlock.Text += String.Format("Unable to calculate the absolute value of {0}.",
                        value) + "\n";
   }
}
// The example displays the following output:
//       Abs(32767) = 32767
//       Abs(10328) = 10328
//       Abs(0) = 0
//       Abs(-1476) = 1476
//       Unable to calculate the absolute value of -32768.
