C# में Single.IsInfinity() मेथड का उपयोग यह दर्शाने के लिए किया जाता है कि निर्दिष्ट संख्या नेगेटिव या पॉजिटिव इनफिनिटी का मूल्यांकन करती है या नहीं।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public static bool IsInfinity (float val);
ऊपर, वैल एकल-सटीक फ़्लोटिंग-पॉइंट संख्या है।
उदाहरण
आइए अब एक उदाहरण देखें -
using System;
public class Demo {
public static void Main(){
float f1 = 19.3f;
float f2 = Single.MaxValue;
Console.WriteLine("Value1 = "+f1);
Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
Console.WriteLine("\nValue2 = "+f2);
Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
Value1 = 19.3 Hashcode for Value1 = 1100637798 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = False Value2 = 3.402823E+38 Hashcode for Value2 = 2139095039 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False
उदाहरण
आइए अब एक और उदाहरण देखें -
using System;
public class Demo {
public static void Main(){
float f1 = 5.0f/0.0f;
float f2 = Single.MinValue;
Console.WriteLine("Value1 = "+f1);
Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
Console.WriteLine("\nValue2 = "+f2);
Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
Value1 = ∞ Hashcode for Value1 = 2139095040 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Value2 = -3.402823E+38 Hashcode for Value2 = -8388609 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False
