Math.Abs Method (SByte)

.NET Framework 4.5

Other Versions

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

This API is not CLS-compliant.

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

Syntax

C++

[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.

Exceptions

Exception	Condition
OverflowException	value equals SByte.MinValue.

Remarks

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.

Examples

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

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.
