# 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;
|
||
|
|
```
