type the variable in the script window without a semicolon then run the code

You got it backwards. Typing the variable name first and then running the code will likely get you a "variable name not defined" error message. You have to do it like I said in my answer below. Run the code first, then execute the variable name without a semicolon.

Or you can simply list the variable all by itself on a line of code:
m = 10.42;
fprintf('m = %f\n', m); % Method 1
disp(m); % Method 2
m % Method 3. Note: no semicolon, just the name.
str = sprintf('%f\n', m) % Yet another method - returns a string

doc fprintf

or disp()
Isabella, a couple of technical notes:
- if you do not specify any file identifier for the fprintf() call, then the default is to go to the command window
- the file identifier 1 (the number) is defined as going to the command window.
