[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents negative infinity. This field is constant.

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

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 += String.Format("10.0 minus NegativeInfinity equals {0}.", (10.0 - Double.NegativeInfinity).ToString()) + "\n";
