C# में Single.IsNan () विधि का उपयोग उस मान को वापस करने के लिए किया जाता है जो इंगित करता है कि निर्दिष्ट मान एक संख्या (NaN) नहीं है।
सिंटैक्स
वाक्य रचना इस प्रकार है -
public static bool IsNaN (float f);
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 = 5.0f/0.0f;
float f2 = 45.5f;
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("\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));
}
} 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 Value2 = 45.5 Hashcode for Value2 = 1110835200 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False Is Value2 NaN? = 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 = 0.0f / 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("\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));
}
} 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 Value2 = NaN Hashcode for Value2 = -4194304 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False Is Value2 NaN? = True
