You can say whatever you want on your web page. But for the Linux Gazette, the
editor will decide, and I hope there will be enough complaints against such a
wrong article.

Where did you see it cannot do that? Do you have an example?

(Note that "%.15f" outputs 15 digits after the decimal point, so this may be
more than 15 digits, taking into account those before the decimal point. You
should use "%.15g" if you want 15 significant digits.)
