Public Const NegativeInfinity As Double
public const double NegativeInfinity


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 MinValue.

Use IsNegativeInfinity to determine whether a value evaluates to negative infinity. It is not possible to determine whether a value evaluates to negative infinity by comparing it to another value equal to NegativeInfinity.


The following example illustrates the use of NegativeInfinity:

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