Read MoreLowercase suffixes in C#
Set lowercase suffixes for literals such as u, l, ul, f, etc.// l for long long a = 29876l;It can be used on literal numbers as well. It tells the compiler that the literal is of a specific type.The following is an example −Example Live Demousing System.IO; using System; public class Program { public static void Main() { long a = 29876l; float b = 95.10f; Console.WriteLine(a); Console.WriteLine(b); } }On running the above example, you will get the following output. With that, you will also get a ...
