There's printf in Bash, and there's printf in C. Why would I have to do it in Bash, when the correct output can come directly from the C program? Besides, I can't readily clean up the trailing zeros with printf, I will still have to do some extra juggling on top of that, to get the answer "0.3". And no, I can't simply tell printf to print me only one digit after the dot, because I don't know beforehand how many digits the answer will have.
