Single.IsNegativeInfinity() Method in C# with Examples
In C#, Single.IsNegativeInfinity(Single) is a Single struct method. This method is used to check whether a specified floating-point 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 (float f);
Parameter:
f: It is a single-precision floating-point number of type System.Single.
Return Type: This function return a boolean value True, if specified value evaluates to negative infinity, otherwise return False.
Example: To demonstrate the Single.IsNegativeInfinity(Single) Method:
// C# program to illustrate the // Single.IsNegativeInfinity(Single) // 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 float zero = 0.0f; float value = -5f; float result = value / zero; // Printing result Console.WriteLine(result); // Check result using IsNegativeInfinity() Method Console.WriteLine(Single.IsNegativeInfinity(result)); // Result of floating point operation // that is less than Single.MinValue // is Negative Infinity result = Single.MinValue * 7.9f; // Printing result Console.WriteLine(result); // Check result using IsNegativeInfinity() Method Console.WriteLine(Single.IsNegativeInfinity(result)); } } |
Output:
-Infinity True -Infinity True
Note:
- The result of any floating point operation that is less than Single.MinValue is considered as Negative Infinity.
- Floating-point operation return PositiveInfinity or NegativeInfinity to indicate the overflow condition.
