Math.Abs Method (Single)

.NET Framework (current version)

Note

The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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

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

Syntax

```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 Abs(Single) method to get the absolute value of a number of Single values.

```using System;

public class Example
{
public static void Main()
{
float[] values= { Single.MaxValue, 16.354e-12F, 15.098123F, 0F,
-19.069713F, -15.058e17F, Single.MinValue };
foreach (float value in values)
Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
}
}
// 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
```
