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 code example illustrates the use of NegativeInfinity:

' This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals " + (10 - Double.NegativeInfinity).ToString() + ".")

            // This will equal Infinity.
            Console.WriteLine("10.0 minus NegativeInfinity equals {0}.", (10.0 - Double.NegativeInfinity).ToString());

// This will equal Infinity.
Console::WriteLine( "10.0 minus NegativeInfinity equals {0}.", (10.0 - Double::NegativeInfinity) );
