Bug #79338 [NEW]: fmod() not calculating properly

From: ziggi at ziggi dot pl Operating system: Windows PHP version: 7.4.3 Package: *Math Functions Bug Type: Bug Bug description:fmod() not calculating properly Description: ------------ --- From manual page: https://php.net/function.fmod --- I would say - simple answer provided by PHP team: "The value that you expect (0) is obtained using float precision. (In C) PHP uses double, and with this type fmod() returns 1.3." I completely pointless. This is not math! This is plain bullshit!!! Perl, MySQL, Python... you name it, all have no problems!!! Test script: --------------- echo fmod(75.6, 25.2); Expected result: ---------------- 0 Actual result: -------------- 25.2 -- Edit bug report at https://bugs.php.net/bug.php?id=79338&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79338&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79338&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79338&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79338&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79338&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79338&r=support Expected behavior: https://bugs.php.net/fix.php?id=79338&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79338&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79338&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79338&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79338&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79338&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79338&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79338&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79338&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79338&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79338&r=mysqlcfg
