# Literal Improvements
 | 
						|
 | 
						|
C# 7.0 allows _ to occur as a ***digit separator*** inside number literals:
 | 
						|
 | 
						|
```
 | 
						|
var d = 123_456;
 | 
						|
var x = 0xAB_CD_EF;
 | 
						|
```
 | 
						|
 | 
						|
You can put them wherever you want between digits, to improve readability. They have no effect on the value.
 | 
						|
 | 
						|
Also, C# 7.0 introduces ***binary literals***, so that you can specify bit patterns directly instead of having to know hexadecimal notation by heart.
 | 
						|
 | 
						|
```
 | 
						|
var b = 0b1010_1011_1100_1101_1110_1111;
 | 
						|
``` |
