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);

    // 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);
