# Math.Abs Method (SByte)

Silverlight

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)

## Syntax

```[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

ExceptionCondition
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 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.

```
