This seems to be a result of MAX_64Bit + 1 being internally interpreted as a float and some kind of rounding error, however I'm not certain that is the case. The failing test is the third from the bottom in the output. I originally found this in 5.3.2 on RHEL 6, but I built a local 5.3.6 and it happens there still as well. bash-4.1# php --version PHP 5.3.6 (cli) (built: Apr 20 2011 09:26:51) Copyright (c) 1997-2011 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2011 Zend Technologies bash-4.1# Expected result: ---------------- --EXPECT-- --- testing: 9223372036854775807 --- int(-9223372036854775808) --- testing: -9223372036854775808 --- int(9223372036854775807) --- testing: 2147483647 --- int(-2147483648) --- testing: -2147483648 --- int(2147483647) --- testing: 9223372034707292160 --- int(-9223372034707292161) --- testing: -9223372034707292160 --- int(9223372034707292159) --- testing: 2147483648 --- int(-2147483649) --- testing: -2147483649 --- int(2147483648) --- testing: 4294967294 --- int(-4294967295) --- testing: 4294967295 --- int(-4294967296) --- testing: 4294967293 --- int(-4294967294) --- testing: 9223372036854775806 --- int(-9223372036854775807) --- testing: 9.2233720368548E+18 --- int(9223372036854775807) --- testing: -9223372036854775807 --- int(9223372036854775806) --- testing: -9.2233720368548E+18 --- int(9223372036854775807) ===DONE=== Actual result: -------------- --- testing: 9223372036854775807 --- int(-9223372036854775808) --- testing: -9223372036854775808 --- int(9223372036854775807) --- testing: 2147483647 --- int(-2147483648) --- testing: -2147483648 --- int(2147483647) --- testing: 9223372034707292160 --- int(-9223372034707292161) --- testing: -9223372034707292160 --- int(9223372034707292159) --- testing: 2147483648 --- int(-2147483649) --- testing: -2147483649 --- int(2147483648) --- testing: 4294967294 --- int(-4294967295) --- testing: 4294967295 --- int(-4294967296) --- testing: 4294967293 --- int(-4294967294) --- testing: 9223372036854775806 --- int(-9223372036854775807) --- testing: 9.2233720368548E+18 --- int(-9223372036854775808) --- testing: -9223372036854775807 --- int(9223372036854775806) --- testing: -9.2233720368548E+18 --- int(9223372036854775807) ===DONE=== ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54578&edit=1
