Defining different types of numbers in C#

You can define a number in various ways in C#,

1F // a float with the value 1
1L // a long with the value 1
1D // a double with the value 1

personally I'm looking for which would a short, however to make the question a better reference for people, what are all the other post-fix's to number literals you can apply?

Type        Suffix    .NET Framework Type                  
-------------------------------------------------------------------------------------
decimal     M or m    System.Decimal
double      D or d    System.Double
float       F or f    System.Single
int         [1]       System.Int32
long        L or l    System.Int64

[1] When an integer literal has no suffix, its type is the first of these types in which its value can be represented: int, uint, long, ulong.

When an integer literal specifies only a U or u suffix, its type is the first of these types in which its value can be represented: uint, ulong.

When an integer literal specifies only a L or l suffix, its type is the first of these types in which its value can be represented: long, ulong.

When an integer literal specifies both a U or u and L or l suffix, its type is the first of these types in which its value can be represented: ulong.

for money:

decimal mon = 1m;

for output:

string curr = String.Format("{0:C}", mon);  //output $1.00
