# Double.PositiveInfinity Field

## Definition

Represents positive infinity. This field is constant.

``public: double PositiveInfinity = Infinity;``
``public const double PositiveInfinity = Infinity;``
``val mutable PositiveInfinity : double``
``Public Const PositiveInfinity As Double  = Infinity``

Value = Infinity
Double

## Examples

The following code example illustrates the use of PositiveInfinity:

``````// This will equal Infinity.
Console::WriteLine( "PositiveInfinity plus 10.0 equals {0}.", (Double::PositiveInfinity + 10.0) );
``````
``````// This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals {0}.", (Double.PositiveInfinity + 10.0).ToString());
``````
``````// This will equal Infinity.
printfn \$"PositiveInfinity plus 10.0 equals {Double.PositiveInfinity + 10.}."
``````
``````' This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals " + (Double.PositiveInfinity + 10).ToString() + ".")
``````

## 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 Double.MaxValue.
