Digit Separators and Binary Literals in C#

In C#7 there are Digit Separators and Binary Literals which were added. One may wonder what these are? Basically you can replace long number values with underscore (_) such that code readability is improved.

Let me give you couple of examples of it to make it clear.

//old way of 
var myBigNumber = 12345678901234567890;

//new way with digital separators
var myBigNumberNewWay = 123_456_789_012_345_678_90;

Neat but it doesn’t end there you can also use it for Binary literals and Hex also, like the examples below, where they all are 2020 the year we all despise 🙂

var myInt = 2020;

var myBinary = 0b11_11_11_00_100;

var myHex = 0x7_E4;

Summary

I hope the C#7 Digital Separators and Binary Literals will give you a hand in writing more clear code 🙂
