From: russ at kdimail dot com Operating system: RedHat Linux 7.3 PHP version: 4.3.3 PHP Bug Type: *Math Functions Bug description: Round and number_format give inconsistent results.
Description: ------------ Round and number_format seem to be rounding the same numbers in different ways, also the output of the "round" function does not match the example given in the php documentation. Round just seems to be always rounding up. Number format seems to be rounding either up or down depending on the value of the number before the decimal point. In my php.ini I have changed precision = 14. Reproduce code: --------------- echo "round 0.045 = " . round(0.045, 2) . "<br>"; echo "number format 0.045 = " . number_format(0.045, 2) . "<br><br>"; echo "round 0.055 = " . round(0.055, 2) . "<br>"; echo "number format 0.055 = " . number_format(0.055, 2) . "<br><br>"; echo "round 5.045 = " . round(5.045, 2) . "<br>"; echo "number format 5.045 = " . number_format(5.045, 2) . "<br><br>"; echo "round 5.055 = " . round(5.055, 2) . "<br>"; echo "number format 5.055 = " . number_format(5.055, 2) . "<br><br>"; echo "round 3.025 = " . round(3.025, 2) . "<br>"; echo "number format 3.025 = " . number_format(3.025, 2) . "<br><br>"; echo "round 4.025 = " . round(4.025, 2) . "<br>"; echo "number format 4.025 = " . number_format(4.025, 2) . "<br><br>"; Actual result: -------------- round 0.045 = 0.05 number format 0.045 = 0.05 round 0.055 = 0.06 number format 0.055 = 0.06 round 5.045 = 5.05 number format 5.045 = 5.04 round 5.055 = 5.06 number format 5.055 = 5.05 round 3.025 = 3.03 number format 3.025 = 3.02 round 4.025 = 4.03 number format 4.025 = 4.03 -- Edit bug report at http://bugs.php.net/?id=25694&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25694&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25694&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25694&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25694&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25694&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25694&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25694&r=support Expected behavior: http://bugs.php.net/fix.php?id=25694&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25694&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25694&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25694&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25694&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25694&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25694&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25694&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25694&r=float
