I am trying to display the value of a using fprintf with only two decimals. Given a = 3.870081e+01;
Can you modify my code below to only display two decimals?
fprintf('The answer for a is %d m/s\n', a)
Thanks,

Ran in:
format long g
a = rand*10
a =
5.92737493941911
fprintf('The answer for a is %.2f m/s\n', a)
The answer for a is 5.93 m/s
