Math.Abs Method (SByte)

Updated: September 2010

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 Math.Abs(SByte) method to get the absolute value of several SByte values.


sbyte[] values = { SByte.MaxValue, 98, 0, -32, SByte.MinValue };
foreach (sbyte 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(127) = 127
//       Abs(98) = 98
//       Abs(0) = 0
//       Abs(-32) = 32
//       Unable to calculate the absolute value of -128.
