Returns the absolute value of an 8-bit signed integer.

This API is not CLS-compliant.

Assembly:  mscorlib (in mscorlib.dll)

public static sbyte Abs(
	sbyte value


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.

using System;

public class Example
    public static void Main()
      sbyte[] values = { SByte.MaxValue, 98, 0, -32, SByte.MinValue };
      foreach (sbyte value in values)
         try {
            Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
         catch (OverflowException) {
            Console.WriteLine("Unable to calculate the absolute value of {0}.", 
// 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.
