The new digit separators

Digit separator is a new feature in C# 7.0. You can use _ (underscore) inside numeric literals as a digit separator. The purpose of it is none other than improving the readability of the value in code.

You can put a digit separator (_) wherever you want between digits. You can have multiple underscores (____) too. They will have no effect on the value. This is shown in the following code snippet:

    var decimalValue1 = 1_50_000; // better than 150000 
    var decimalValue2 = 25_91_50_000; // better than 259150000 
 
    // you can use multiple underscores too 
    var decimalValue3 = 25_91__50___000; // better than 259150000 

You can also add digit separators to a binary literal and/or hexadecimal literals:

    var binaryValue = 0b1010_1011_1100_1101_1110_1111; 
    var hexadecimalValue = 0xAB_C_0_D_EF_578;
