C# में Double.IsNegativeInfinity() विधि का उपयोग यह दर्शाने के लिए किया जाता है कि निर्दिष्ट संख्या ऋणात्मक अनंतता का मूल्यांकन करती है या नहीं।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public static bool IsNegativeInfinity (double val);
ऊपर, वैल एक डबल-सटीक फ़्लोटिंग-पॉइंट नंबर है।
उदाहरण
आइए अब एक उदाहरण देखें -
using System;
public class Demo {
public static void Main(){
double d = 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));
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Double Value = NaN HashCode of Double Value = -524288 TypeCode of Double Value = Double Positive Infinity? = False Check whether the specified value is NaN? = True Does the value evaluate to negative infinity? = False
उदाहरण
आइए अब एक और उदाहरण देखें -
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));
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Double Value = -∞ HashCode of Double Value = -1048576 TypeCode of Double Value = Double Positive Infinity? = True Check whether the specified value is NaN? = False Does the value evaluate to negative infinity? = True
