Literal suffix

You can use suffix to define literals explicitly.

The following table lists the suffix used by C#.

Letter	C# type	Example
F	float	f = 1.0F;
D	double	d = 1D;
M	decimal	decimal d = 1.0M;
U	uint or ulong	uint i = 1U;
L	long or ulong	ulong i = 1UL;


using System;

class Program
{
    static void Main(string[] args)
    {

        Console.WriteLine(1D.GetType());

        Console.WriteLine(1.6F.GetType());

        Console.WriteLine(1.1M.GetType());

        Console.WriteLine(1U.GetType());

        Console.WriteLine(1UL.GetType());
    }
}

The output:


System.Double
System.Single
System.Decimal
System.UInt32
System.UInt64

We can use the suffix when initializing the variables as well.


using System;

class Program
{
    static void Main(string[] args)
    {
        decimal d = 1.1M;
        Console.WriteLine(d);

    }
}

The output:

1.1
