C# में Double.IsPositiveInfinity() मेथड यह दर्शाने वाला मान लौटाता है कि निर्दिष्ट संख्या पॉजिटिव इन्फिनिटी का मूल्यांकन करती है या नहीं।
सिंटैक्स
सिंटैक्स इस प्रकार है -
public static bool IsPositiveInfinity (double val);
उपरोक्त, val एक डबल-प्रिसिजन फ्लोटिंग-पॉइंट नंबर है।
उदाहरण 1
using System;
public class Demo {
public static void Main() {
double d = 1.0/0.0;
Console.WriteLine("Double Value = " + d);
Console.WriteLine("HashCode of Double Value = " + d.GetHashCode());
TypeCode type = d.GetTypeCode();
Console.WriteLine("TypeCode of Double Value = " + type);
Console.WriteLine("Positive Infinity? = " + Double.IsInfinity(d));
Console.WriteLine("Check whether the specified value is NaN? = " + Double.IsNaN(d));
Console.WriteLine("Does the value evaluate to negative infinity? = " + Double.IsNegativeInfinity(d));
Console.WriteLine("Does the value evaluate to positive infinity? = " + Double.IsPositiveInfinity(d));
}
}
