Aligning numbers with text in a table

In the code below, the numbers all occupy 13 characters of space. How do you align the words and numbers so each word also occupies 13 characters of space like in the example below the code?

fprintf('%.13s %.13s %.13s %.13s \n', 'a', 'yes','async','asychronous'); 
fprintf('%3.10f %3.10f %3.10f %3.10f', 33.12, 5.3819, 291.210, 39.2111); 

a yes async asychronous

33.1200000000 5.3819000000 291.2100000000 39.2111000000

% 13 characters and aligned to the right:
fprintf('%13s %13s %13s %13s \n', 'a', 'yes','async','asychronous');

            a           yes         async   asychronous 

% 13 characters and aligned to the left:
fprintf('%-13s %-13s %-13s %-13s \n', 'a', 'yes','async','asychronous'); 

a             yes           async         asychronous   

fprintf('%3.10f %3.10f %3.10f %3.10f', 33.12, 5.3819, 291.210, 39.2111);

33.1200000000 5.3819000000 291.2100000000 39.2111000000

It was only the "." which is not used for the %s format.
