## Definition

`public: double NegativeInfinity = -Infinity;`

`public const double NegativeInfinity = -Infinity;`

`val mutable NegativeInfinity : double`

`Public Const NegativeInfinity As Double = -Infinity`

#### Field Value

## Examples

The following code example illustrates the use of NegativeInfinity:

```
// This will equal Infinity.
Console::WriteLine( "10.0 minus NegativeInfinity equals {0}.", (10.0 - Double::NegativeInfinity) );
```

```
// This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals {0}.", (10.0 - Double.NegativeInfinity).ToString());
```

```
' This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals " + (10 - Double.NegativeInfinity).ToString() + ".")
```

## Remarks

The value of this constant is the result of dividing a negative number by zero.

This constant is returned when the result of an operation is less than Double.MinValue.

Use IsNegativeInfinity to determine whether a value evaluates to negative infinity.
