C # 6.0 (C # VNext) new features: Numeric Literal Formats

Numeric Literal Formats = Binary literals and separators
The individual is interpreted as "2-bit (2-digit) name and delimiter"

Previously available, mainly on decimal and 10-bit carry-over as follows:

var num1 = 1234; 10 decimal var num2 = 0x1234; 16 Rounding

2 name How do you pronounce it?

var num3 = 0b1010; 2 carry, the 10 digit represented is 10

And when we use the 2 to declare the name, that number will suddenly be very long, for example:

var NUM10 = 12345;var num2 = 0b11000000111001;

At this point, we can add the delimiter (Separator):

var num2 = 0b11_0000_0011_1001;

It's easier to see each number in this way.

The delimiter can be used in other numeric types name as follows:

var num5 = 1_234_567_890; 10 rounding: expressed as 123456789var num6 = 0XFF_FA_88_BC; 16 Rounding: Replace with 10 for 4294609084var num7 = 0b10_01__01_10; 2 rounding: 10 for 150

Finally, let's look at an example:

[Serializable] [Flags] [System.Runtime.InteropServices.ComVisible (True)]public enum fileattributes{  ReadOnly =          0b00_00_00_00_00_ 00_01,//0x0001  Hidden =            0b00_00_00_00_00_00_10,//0x0002  System =            0b00_00_00_00_00_01_00,//0x0004  Directory =         0b00_00_00_00_00_10_00,//0x0010  Archive =           0b00_00_00_00_01_00_00,//0x0020  Device =            0b00_00_00_00_10_00_00,//0x0040  Normal =            0b00_00_00_01_00_00_00,//0x0080  temporary =         0b00_00_00_10_00_00_00,//0x0100  Sparsefile =        0b00_00_01_00_00_00_00,//0x0200  reparsepoint =      0b00_00_10_00_00_00_00,//0x0400  compressed =        0b00_01_00_00_00_00_00,//0x0800  Offline =           0b00_10_00_00_00_00_00,//0x1000  notcontentindexed = 0b01_00_00_00_00_00_00,//0x2000  Encrypted =         0b10_00_00_00_00_00_00  //0x4000}
