A double is similar to the int except that a double allows for decimal places.

As an example, if you wanted to display the number 10.666666666 or 10.4 you could use a double. If you wanted to display a number like 5000 or 4 you could use an int.

Here is an example of how to use a double:

double pitch = 10.666666666;

The word ‘double’ is a type which tells the computer what type of variable you want to use. Following this by the word ‘pitch’ (you can pick your own word here), I am assigning the double to a variable called ‘pitch’

Another way to think of it is that I have a double (type) and I am placing inside of a box(Variable) named ‘pitch’

By doing ‘=’ followed by a decimal number such as 10.666666, you are assigning the double called ‘pitch’ a value.

To print this on the console you need to use the Console.WriteLine() function which looks like this: –

Console.WriteLine(pitch);

This is tells the computer to print a line on the console that contains the content of the variable assigned the name ‘pitch’

Put the two lines together…

double pitch = 10.666666666;
Console.WriteLine(pitch);

…and this is the result that gets printed on the console:

10.666666666
