Req #80697 [NEW]: Return type declaration int allows floats to be returned

From: david dot m dot wakelin at gmail dot com Operating system: Ubuntu 18.04.5 LTS PHP version: 8.0.1 Package: *Programming Data Structures Bug Type: Feature/Change Request Bug description:Return type declaration int allows floats to be returned Description: ------------ When specifying int as a return type declaration, a type of float is allowed to be returned, which gets cast to an int. All other type coercions preserve the meaning of the returned data, whereas coercing float to int will lose information after the decimal, therefore not returning the true meaning. This is not a good feature in my opinion and has been the cause of a couple of uncaught bugs for me. I suggest that a float to int should be non-coercible in return types and should raise a TypeError as standard and not just when using strict_types. Test script: --------------- class Test { public static function getInt(): int { return 5.67; } } Test::getInt(); // 5 but would like to see a TypeError Expected result: ---------------- getInt returns a 5, but I think it should raise a TypeError -- Edit bug report at https://bugs.php.net/bug.php?id=80697&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80697&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80697&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80697&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80697&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80697&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80697&r=support Expected behavior: https://bugs.php.net/fix.php?id=80697&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80697&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80697&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80697&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80697&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80697&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80697&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80697&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80697&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80697&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80697&r=mysqlcfg
