note 103755 added to function.sprintf

Here is how to print a floating point number with 16 significant digits regardless of magnitude: <?php $result = sprintf(sprintf('%%.%dF', max(15 - floor(log10($value)), 0)), $value); ?> This works more reliably than doing something like sprintf('%.15F', $value) as the latter may cut off significant digits for very small numbers, or prints bogus digits (meaning extra digits beyond what can reliably be represented in a floating point number) for very large numbers. ---- Server IP: 69.147.83.197 Probable Submitter: 83.160.79.214 ---- Manual Page -- http://www.php.net/manual/en/function.sprintf.php Edit -- https://master.php.net/note/edit/103755 Del: integrated -- https://master.php.net/note/delete/103755/integrated Del: useless -- https://master.php.net/note/delete/103755/useless Del: bad code -- https://master.php.net/note/delete/103755/bad+code Del: spam -- https://master.php.net/note/delete/103755/spam Del: non-english -- https://master.php.net/note/delete/103755/non-english Del: in docs -- https://master.php.net/note/delete/103755/in+docs Del: other reasons-- https://master.php.net/note/delete/103755 Reject -- https://master.php.net/note/reject/103755 Search -- https://master.php.net/manage/user-notes.php
