Digit Separator

C# digit separator is a new feature, introduced in C# 7.0. It allows us to separate digits using comma (,) separator. This concept is used to make numerical values readable.

When we have a large numeric value, reading of this value may be incorrect. To avoid this error, C# provides digit separator concept.

See, the following example that implements this concept.

C# Digit Separator Example

using System;
namespace CSharpFeatures
{
    class DigitSeperatorExample
    {
        public static void Main(string[] args)
        {
            // Seperating digits using underscore
            int i = 1_00_000;
            double f = 1_00_000; 
            Console.WriteLine(i);
            Console.WriteLine(f);
        }
    }
}

Output:

100000
100000
