Public Const PositiveInfinity As Double
public const double 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 example illustrates the use of PositiveInfinity:

' This will equal Infinity.
outputBlock.Text &= "PositiveInfinity plus 10.0 equals " + (Double.PositiveInfinity + 10).ToString() + "." & vbCrLf
// This will equal Infinity.
outputBlock.Text += String.Format("PositiveInfinity plus 10.0 equals {0}.", (Double.PositiveInfinity + 10.0).ToString()) + "\n";
