# Math.Abs Method (Double)

.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 double-precision floating-point number.

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

## Syntax

```public static double Abs(
double value
)
```

#### Parameters

value
Type: System.Double

A number that is greater than or equal to Double.MinValue, but less than or equal to Double.MaxValue.

#### Return Value

Type: System.Double

A double-precision floating-point number, x, such that 0 x Double.MaxValue.

## Remarks

The absolute value of a Double is its numeric value without its sign. For example, the absolute value of both 1.2e03 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(Double) method to get the absolute value of a number of Double values.

```using System;

public class Example
{
public static void Main()
{
double[] doubles = { Double.MaxValue, 16.354e-17, 15.098123, 0,
-19.069713, -15.058e18, Double.MinValue };
foreach (double value in doubles)
Console.WriteLine("Abs({0}) = {1}", value, Math.Abs(value));
}
}
// The example displays the following output:
//       Abs(1.79769313486232E+308) = 1.79769313486232E+308
//       Abs(1.6354E-16) = 1.6354E-16
//       Abs(15.098123) = 15.098123
//       Abs(0) = 0
//       Abs(-19.069713) = 19.069713
//       Abs(-1.5058E+19) = 1.5058E+19
//       Abs(-1.79769313486232E+308) = 1.79769313486232E+308
```
