Now multiply variable x 100 and now set type of variable to "integer" with function "settype" and print this variable. Result will for example: 1989, even that correct result is 1990. This make only, when original value is 16.90 or 17.90 or 18.90 or 19.90. If is original value another (for example 10.90 or 19.80), result will be correct (for example 1090 or 1980), but now is result incorrect for example 1989. Test script: --------------- <?php $double = 19.90; // Only 16.90 or 17.90 or 18.90 or 19.90 will print bad result $integer = $double*100; // Now is value 1990 settype($integer, 'integer'); // This change value to 1989 - bug echo $integer; Expected result: ---------------- Value of "integer" - 1990 Actual result: -------------- Value of "integer" - 1989 -- Edit bug report at https://bugs.php.net/bug.php?id=64534&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64534&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64534&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64534&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64534&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64534&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64534&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64534&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64534&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64534&r=support Expected behavior: https://bugs.php.net/fix.php?id=64534&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64534&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64534&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64534&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64534&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64534&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64534&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64534&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64534&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64534&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64534&r=mysqlcfg
