Is there a readable way to put millions into c# code?

Question

This is a little hard to read:

int x = 100000000;

Is there an easy way to write:

int x = 100,000,000;

So that the scale is obvious?

Please note this is NOT about formatting the output.

Answer 1

Starting with C#7 you will be able to use the underscore-char (_) to seperate digit groups. The underscore can be placed anywhere in a number. A simple example:

const int MILLION = 1_000_000;

You can place the _ anywhere you want and can even combine it with integer literals:

const int USHORT_MAX = 0xFF_FF;

Or even with floats and decimals, even after the decimal sign:

const decimal SMALL_VALUE = 0.000_000_001;
