C# में Single.IsPositiveInfinity() मेथड और उदाहरण

C# में Single.IsPositiveInfinity() मेथड यह जांचता है कि निर्दिष्ट फ्लोट मान धनात्मक अनंत (positive infinity) है या नहीं। यह bool मान लौटाता है।

सिंटैक्स

public static bool IsPositiveInfinity (float val);

पैरामीटर val एक सिंगल-प्रिसिजन फ्लोटिंग-पॉइंट नंबर है।

उदाहरण 1: धनात्मक और ऋणात्मक अनंत की जांच

using System; 

public class Demo { 
    public static void Main() { 
        float f1 = -25.0f/0.0f; // Negative Infinity
        float f2 = 5.0f/0.0f;   // Positive Infinity
        
        Console.WriteLine("Value1 = " + f1);
        Console.WriteLine("Hashcode for Value1 = " + f1.GetHashCode());
        Console.WriteLine("TypeCode for Value1 = " + f1.GetTypeCode());
        Console.WriteLine("Is Value1 infinity? = " + Single.IsInfinity(f1));
        Console.WriteLine("Is Value1 NaN? = " + Single.IsNaN(f1));
        Console.WriteLine("Is Value1 positive infinity? = " + Single.IsPositiveInfinity(f1));
        
        Console.WriteLine("\nValue2 = " + f2);
        Console.WriteLine("Hashcode for Value2 = " + f2.GetHashCode());
        Console.WriteLine("TypeCode for Value2 = " + f2.GetTypeCode());
        Console.WriteLine("Is Value2 infinity? = " + Single.IsInfinity(f2));
        Console.WriteLine("Is Value2 NaN? = " + Single.IsNaN(f2));
        Console.WriteLine("Is Value2 positive infinity? = " + Single.IsPositiveInfinity(f2));
    } 
}

आउटपुट

Value1 = -∞
Hashcode for Value1 = -8388608
TypeCode for Value1 = Single
Is Value1 infinity? = True
Is Value1 NaN? = False
Is Value1 positive infinity? = False

Value2 = ∞
Hashcode for Value2 = 2139095040
TypeCode for Value2 = Single
Is Value2 infinity? = True
Is Value2 NaN? = False
Is Value2 positive infinity? = True

उदाहरण 2: सामान्य मान और धनात्मक अनंत की तुलना

using System; 

public class Demo { 
    public static void Main() { 
        float f1 = 10.0f/0.0f; // Positive Infinity
        float f2 = -3.0f;      // सामान्य ऋणात्मक मान
        
        Console.WriteLine("Value1 = " + f1);
        Console.WriteLine("Hashcode for Value1 = " + f1.GetHashCode());
        Console.WriteLine("TypeCode for Value1 = " + f1.GetTypeCode());
        Console.WriteLine("Is Value1 infinity? = " + Single.IsInfinity(f1));
        Console.WriteLine("Is Value1 NaN? = " + Single.IsNaN(f1));
        Console.WriteLine("Is Value1 positive infinity? = " + Single.IsPositiveInfinity(f1));
        
        Console.WriteLine("\nValue2 = " + f2);
        Console.WriteLine("Hashcode for Value2 = " + f2.GetHashCode());
        Console.WriteLine("TypeCode for Value2 = " + f2.GetTypeCode());
        Console.WriteLine("Is Value2 infinity? = " + Single.IsInfinity(f2));
        Console.WriteLine("Is Value2 NaN? = " + Single.IsNaN(f2));
        Console.WriteLine("Is Value2 positive infinity? = " + Single.IsPositiveInfinity(f2));
    } 
}
