# Double.PositiveInfinity Field

.NET Framework 1.1

Represents positive infinity. This field is constant.

```[Visual Basic]
Public Const PositiveInfinity As Double
[C#]
public const double PositiveInfinity;
[C++]
public: const double PositiveInfinity;
[JScript]
public var PositiveInfinity : double;```

#### Remarks

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

This constant is returned when the result of an operation is greater than MaxValue.

Use IsPositiveInfinity to determine whether a value evaluates to positive infinity. It is not possible to determine whether a value evaluates to positive infinity by comparing it to another value equal to PositiveInfinity.

#### Example

[Visual Basic, C#, C++] The following code sample illustrates the use of PositiveInfinity:

```[Visual Basic]
' This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals " + (Double.PositiveInfinity + 10).ToString() + ".")

[C#]
// This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals {0}.", (Double.PositiveInfinity + 10.0).ToString());

[C++]
// This will equal Infinity.
Console::WriteLine(S"PositiveInfinity plus 10.0 equals {0}.", __box((Double::PositiveInfinity + 10.0)));
```
