From: joerg dot klein at ifsam dot lu Operating system: win2000 PHP version: 5.0.0 PHP Bug Type: *Math Functions Bug description: round() and number_format() calculates wrong
Description: ------------ I use a fomular as the first paramter and the result is wrong. When brackets were set, the result is correct, but this makes no sense to me. Reproduce code: --------------- echo round(0.35*90/100); echo number_format(0.35*90/100, 2, ".", ""); to get the correct result I should use the following syntax: echo round(0.35* (90/100) ) echo number_format(0.35* (90/100) , 2, ".", ""); Expected result: ---------------- 0.32 0.32 Actual result: -------------- 0.31 0.31 -- Edit bug report at http://bugs.php.net/?id=30048&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30048&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30048&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30048&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30048&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30048&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30048&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30048&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30048&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30048&r=support Expected behavior: http://bugs.php.net/fix.php?id=30048&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30048&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30048&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30048&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30048&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30048&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30048&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30048&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30048&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30048&r=mysqlcfg
