Literals

There are a couple of minor additional capabilities and readability enhancements when specifying literal values in code. You can specify binary literals, which means you don't have to work out how to represent them using a different base anymore. You can also put underscores anywhere within a literal to make it easier to read the number. The underscores are ignored but allow you to separate digits into convention groupings. This is particularly well suited to the new binary literal as it can be very verbose, listing out all those zeros and ones.

Take the following example that uses the new 0b prefix to specify a binary literal that will be rendered as an integer in a string:

Console.WriteLine($"Binary solo! {0b0000001_00000011_000000111_00001111}");

You can do this with other bases too, such as this integer, which is formatted to use a thousands separator:

Console.WriteLine($"Over {9_000:#,0}!"); // Prints "Over 9,000!"
