Bug #68473 [NEW]: number_format results on high numbers?

From: php at kingsquare dot nl Operating system: n/a PHP version: 5.6.3 Package: *General Issues Bug Type: Bug Bug description:number_format results on high numbers? Description: ------------ We're seeing issues with number_format and strange behaviour. It seems to be rounding off / exceeding some kind of _undocumented_ limit ? (related bug: 62792, but the response there is irrelevant since the PHP_INT_MAX isnt even reached in some cases and still the error persists? And before you go 'floating points and limited percision: this is an int, not a float... :) ) Test script: --------------- <?php echo PHP_INT_MAX.PHP_EOL; echo number_format(PHP_INT_MAX, 0, '', '').PHP_EOL; // ? echo '4'.PHP_EOL; echo number_format(4, 0, '', '').PHP_EOL; // as expected echo '23372036854775807'.PHP_EOL; echo number_format('23372036854775807', 0, '', '').PHP_EOL; // still errors echo '3372036854775807'.PHP_EOL; echo number_format('3372036854775807', 0, '', '').PHP_EOL; // yeah! the same results :) Expected result: ---------------- 9223372036854775807 9223372036854775807 4 4 23372036854775807 23372036854775807 3372036854775807 3372036854775807 Actual result: -------------- 9223372036854775807 9223372036854775808 4 4 23372036854775807 23372036854775808 3372036854775807 3372036854775807 -- Edit bug report at https://bugs.php.net/bug.php?id=68473&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68473&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68473&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68473&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68473&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68473&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68473&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68473&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68473&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68473&r=support Expected behavior: https://bugs.php.net/fix.php?id=68473&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68473&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68473&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68473&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68473&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68473&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68473&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68473&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68473&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68473&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68473&r=mysqlcfg
