ID: 42487 Updated by: jani@php.net Reported By: gerhard dot mueller at travian dot org -Status: Open +Status: Bogus Bug Type: Math related Operating System: Linux Debian PHP Version: 5.2.3 New Comment: Precision has nothing to do with this. Previous Comments: ------------------------------------------------------------------------ [2007-08-30 13:17:18] gerhard dot mueller at travian dot org Description: ------------ The php.ini setting of "precision" seems to be ignored and is always 6. I makes no difference when you override it with ini_set() or directly in php.ini. tested on 5.1.6, 5.2.2 and 5.2.3 on several Linux Servers and 2 Windows PCs. Only in 5.1.6 change of "precision" was not ignored. Example in php.ini ; The number of significant digits displayed in floating point numbers. precision = 12 Same as this report but bug has nothing to do with round() http://bugs.php.net/bug.php?id=42484 Reproduce code: --------------- ini_set('precision','6'); $big_int = (float)1200000; print "precision6: $big_int \n\n"; ini_set('precision','12'); $big_int = (float)1200000; print "precision12: $big_int"; Expected result: ---------------- precision6: 1.2E+006 precision12: 1200000 Actual result: -------------- precision6: 1.2E+006 precision12: 1.2E+006 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42487&edit=1
