Math.Abs Method (SByte)

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

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public static sbyte Abs(
	sbyte value
)

Parameters

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.

ExceptionCondition
OverflowException

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}.", 
                              value);
         }
      }
   }
}
// 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.
