Double.IsNegativeInfinity() Method in C#

  • Last Updated : 23 Aug, 2021

In C#, Double.IsNegativeInfinity() is a Double struct method. This method is used to check whether a specified value evaluates to negative infinity or not. In some floating point operation, it is possible to obtain a result that is negative infinity. For Example: If any negative value is divided by zero, it results in negative infinity.

Syntax: public static bool IsNegativeInfinity (double d); 
Parameter: 
d: It is a double-precision floating-point number of type System.Double
 

Return Type: This function return a Boolean value True, if the specified value evaluates to negative infinity, otherwise return False.

Example:  

Input  : d = -5.0 / 0.0 
Output : True

Input  : d = -1.5935e250 * 7.948e110
Output : True

Code: To demonstrate the Double.IsNegativeInfinity(Double) Method



C#




// C# program to illustrate the
// Double.IsNegativeInfinity() Method
using System;
 
class GFG {
 
    // Main method
    static public void Main()
    {
 
        // Dividing a negative number by zero
        // results in Negative infinity.
 
        // Dividing a number directly by 0
        // produces an error
        // So 0 is stored in a variable first
 
        double zero = 0.0;
        double value = -5;
        double result = value / zero;
 
        // Printing result
        Console.WriteLine(result);
 
        // Check result using IsNegativeInfinity() Method
        Console.WriteLine(Double.IsNegativeInfinity(result));
 
        // Result of floating point operation
        // that is less than Double.MinValue
        // is Negative Infinity
 
        result = Double.MinValue * 7.948e110;
 
        // Printing result
        Console.WriteLine(result);
 
        // Check result using IsNegativeInfinity() Method
        Console.WriteLine(Double.IsNegativeInfinity(result));
    }
}
Output: 
-Infinity
True
-Infinity
True

 

Note: 

  • The result of any floating point operation is less than Double.MinValue (i.e -1.7976931348623157E+308 ) is considered as Negative Infinity.
  • Floating-point operation return Infinity (Positive Infinity) or -Infinity (Negative Infinity) to indicate an overflow condition.
