Single.IsNegative() Method in C# with Examples

Single.IsNegativeInfinity() Method in C# with Examples

Single.IsNegative(Single) Method is used to return a value indicating whether the specified number evaluates to negative or not.

Syntax: public static bool IsNegative (float f);

Return Value: This method returns the true if f evaluates to Negative otherwise it returns false.

Below programs illustrate the use of Single.IsNegative() Method:

Example 1:

// C# program to demonstrate the 
// Single.IsNegative() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        float value1 = 1011.5615f; 
  
        // using IsNegative() method 
        bool value = Single.IsNegative(value1); 
  
        // Displaying the result 
        if (value) 
            Console.WriteLine("{0} is Negative", value1); 
        else
            Console.WriteLine("{0} is not Negative", value1); 
    } 
} 

Output:

1011.562 is not Negative

Example 2:

// C# program to demonstrate the 
// Single.IsNegative() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        float value1 = -10.651f; 
  
        // using IsNegative() method 
        bool value = Single.IsNegative(value1); 
  
        // Displaying the result 
        if (value) 
            Console.WriteLine("{0} is Negative", value1); 
        else
            Console.WriteLine("{0} is not Negative", value1); 
    } 
} 

Output:

-10.651 is Negative
