Answer 1

To align to your system's settings and limitations, you could use serialize_precision to get the most accurate result possible.

echo rtrim(sprintf('%.'.ini_get('serialize_precision').'f', $ret));

I do not recommend using the non-locale aware %F since your question only makes sense for display purposes. Respecting locale makes for a better UX.
