Displaying a value using fprintf with certain number of decimals.

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,

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
