C# এ Single.IsNegative() পদ্ধতিটি একটি মান প্রদান করে যা নির্দেশ করে যে নির্দিষ্ট সংখ্যাটি ঋণাত্মক অসীমতার মূল্যায়ন করে কিনা।
সিনট্যাক্স
সিনট্যাক্স নিম্নরূপ -
public static bool IsNegativeInfinity (float val);
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 = 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("Is Value1 a negative infinity? = "+Single.IsNegativeInfinity(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 negative infinity? = "+Single.IsNegativeInfinity(f2)); } }
