This is wrong; it should be "%d" for integer, or better, change your account variable type to something that could represent the 0.50 you're surcharging. I don't recommend you to using (imprecise) floats for money either. You don't want to withdraw 10.499999997 when you meant 10.5. You need to think about the precision and rounding rules you'd use. AFAIK these are both mandated by laws or something.
