Compiler bugs are not PHP bugs. Previous Comments: ------------------------------------------------------------------------ [2005-07-06 20:16:09] ruslan_y at list dot ru I've made some research and got the solution... If I'm using gcc4 the round() function is broken --- #gcc -v ... gcc version 4.0.0 20050519 (Red Hat 4.0.0-8) --- but after installing gcc2.96 and recompiling php (./configure; make) --- #gcc -v ... gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-126) --- round() works just fine. ------------------------------------------------------------------------ [2005-07-06 13:45:47] ruslan_y at list dot ru It's all right with php5-latest (php5-200507060830) I've got the results as expected: 0.112=>0.11 0.115=>0.12 0.105=>0.11 0.107=>0.11 But It's still a problem with (php4-STABLE-200507060848) on this server. I'm try to reproduce problem on the same version of php on other server (ALT Linux) and did not get any trouble. So it's seems to be Fedora specific (IMHO) ------------------------------------------------------------------------ [2005-07-06 12:27:03] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2005-07-06 11:27:04] ruslan_y at list dot ru Description: ------------ It's something wrong with round() and number_format() function on "new" Fedora Core 4.
