Examples

The following code example illustrates the use of IsNegativeInfinity:

// This will return "true".
Console.WriteLine("IsNegativeInfinity(-5.0 / 0) == {0}.", Double.IsNegativeInfinity(-5.0 / 0) ? "true" : "false");
if (d > Double.MaxValue)
   Console.WriteLine("Your number is bigger than a double.");
// This will equal Infinity.
Console.WriteLine("10.0 minus NegativeInfinity equals {0}.", (10.0 - Double.NegativeInfinity).ToString());

Remarks

Floating-point operations return NegativeInfinity to signal an overflow condition.
