সি# এ Single.IsNan() পদ্ধতিটি এমন একটি মান ফেরত দিতে ব্যবহৃত হয় যা নির্দেশ করে যে নির্দিষ্ট মানটি একটি সংখ্যা (NaN) নয়।
সিনট্যাক্স
সিনট্যাক্স নিম্নরূপ -
public static bool IsNaN (float f);
উপরে, প্যারামিটার ভ্যাল হল একটি একক-নির্ভুল ফ্লোটিং-পয়েন্ট সংখ্যা।
উদাহরণ
আসুন এখন একটি উদাহরণ দেখি -
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));
}

উদাহরণ
এখন আরেকটি উদাহরণ দেখা যাক -
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));
