C# में Single.IsPositiveInfinity () विधि का उपयोग यह दर्शाने के लिए किया जाता है कि निर्दिष्ट संख्या सकारात्मक अनंत का मूल्यांकन करती है या नहीं।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public static bool IsPositiveInfinity (float val);
ऊपर, पैरामीटर वैल एकल-सटीक फ़्लोटिंग-पॉइंट संख्या है।
उदाहरण
आइए अब एक उदाहरण देखें -
using System;
public class Demo {
public static void Main() {
float f1 = -25.0f/0.0f;
float f2 = 5.0f/0.0f;
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("Is Value1 NaN? = "+Single.IsNaN(f1));
Console.WriteLine("Is Value1 a 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 value is positive or negative infinity? = "+Single.IsInfinity(f2));
Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
Console.WriteLine("Is Value2 a positive infinity? = "+Single.IsPositiveInfinity(f2));
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Value1 = -∞ Hashcode for Value1 = -8388608 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Is Value1 NaN? = False Is Value1 a positive infinity? = False Value2 = ∞ Hashcode for Value2 = 2139095040 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = True Is Value2 NaN? = False Is Value2 a positive infinity? = True
उदाहरण
आइए अब एक और उदाहरण देखें -
using System;
public class Demo {
public static void Main() {
float f1 = 10.0f/0.0f;
float f2 = -3.0f;
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("Is Value1 NaN? = "+Single.IsNaN(f1));
Console.WriteLine("Is Value1 a 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 value is positive or negative infinity? = "+Single.IsInfinity(f2));
Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
Console.WriteLine("Is Value2 a positive infinity? = "+Single.IsPositiveInfinity(f2));
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Value1 = ∞ Hashcode for Value1 = 2139095040 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Is Value1 NaN? = False Is Value1 a positive infinity? = True Value2 = -3 Hashcode for Value2 = -1069547520 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False Is Value2 NaN? = False Is Value2 a positive infinity? = False
