Re: Change default serialize precision from 100 to 17

> ini_set('precision', 17); After some testings, here is what I get : <?php ini_set('precision', 14); echo 0.1; // 0.1 echo 0.2; // 0.2 echo 0.3; // 0.3 ini_set('precision', 17); echo 0.2; // 0.10000000000000001 echo 0.2; // 0.20000000000000001 echo 0.3; // 0.29999999999999999 ?> The default precision of 14 (or 12) must have been chosen to address this overlong string representation of many simple floats ? While I agree with you that any data loss must be forbidden, couldn't this also break existing code ? Would it be possible to "displays a value based on the shortest decimal fraction that rounds correctly back to the true binary value", like python 2.7 and 3.1 do ? (http://docs.python.org/tutorial/floatingpoint.html) Just my 2cts :) Nicolas
