Bug #78660 [NEW]: Round works different on PHP 7.4

From: s dot sayakci at shopware dot com Operating system: Linux (NixOs) PHP version: 7.4.0RC3 Package: *Math Functions Bug Type: Bug Bug description:Round works different on PHP 7.4 Description: ------------ We did found that round does work in different way in PHP 7.4 so our Tests are currently failing. I checked the https://www.php.net/manual/en/migration74.incompatible.php and could not found any change on round function. When you pass -1 as float to round we got 0 until PHP 7.4, now we get also -1. Is this change intended? Cause its not mentioned. 3v4l: https://3v4l.org/eLXVb Test script: --------------- var_dump((string) round((float) "-0", 2)); -- Edit bug report at https://bugs.php.net/bug.php?id=78660&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78660&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78660&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78660&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78660&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78660&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78660&r=support Expected behavior: https://bugs.php.net/fix.php?id=78660&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78660&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78660&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78660&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78660&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78660&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78660&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78660&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78660&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78660&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78660&r=mysqlcfg
