A new syntatic sugar has been added to C# 7, which is the digit separator. This construct greatly improves code readability, especially when handling large numbers of different numeric types supported in C#. Prior to C# 7, manipulating large numeric values to have separators was a bit messy and unreadable. With the introduction of the digit separator, you can now use an underscore (_) as a separator for digits:
var longDigit = 2_300_400_500_78;
Also newly introduced in this version is binary literals. You can now create binary literals by simply including 0b as a prefix to binary values:
var binaryValue = 0b11101011;
