# Math.Abs Method (Single)

Silverlight

Updated: September 2010

Returns the absolute value of a single-precision floating-point number.

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

## Syntax

```[SecuritySafeCriticalAttribute]
public static float Abs(
float value
)
```

#### Parameters

value
Type: System.Single
A number that is greater than or equal to Single.MinValue, but less than or equal to Single.MaxValue.

#### Return Value

Type: System.Single
A single-precision floating-point number, x, such that 0 x Single.MaxValue.

## Remarks

The absolute value of a Single is its numeric value without its sign. For example, the absolute value of both 1.2e-03 and -1.2e03 is 1.2e03.

If value is equal to NegativeInfinity or PositiveInfinity, the return value is PositiveInfinity. If value is equal to NaN, the return value is NaN.

## Examples

The following example uses the Math.Abs(Single) method to get the absolute value of several Single values.

```
float[] values = { Single.MaxValue, 16.354e-12F, 15.098123F, 0F,
-19.069713F, -15.058e17F, Single.MinValue };
foreach (float value in values)
outputBlock.Text += String.Format("Abs({0}) = {1}", value, Math.Abs(value)) + "\n";

// The example displays the following output:
//       Abs(3.402823E+38) = 3.402823E+38
//       Abs(1.6354E-11) = 1.6354E-11
//       Abs(15.09812) = 15.09812
//       Abs(0) = 0
//       Abs(-19.06971) = 19.06971
//       Abs(-1.5058E+18) = 1.5058E+18
//       Abs(-3.402823E+38) = 3.402823E+38

```
