Single.PositiveInfinity Field

Represents positive infinity. This field is constant.

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

public const float PositiveInfinity

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.

The following code example demonstrates the PositiveInfinity constant.


// This will equal Infinity.
Console.WriteLine("PositiveInfinity plus 10.0 equals {0}.", (Single.PositiveInfinity + 10.0).ToString());
