Everytime I use the negative PHP_INT_MAX literally (-9223372036854775808) as a function parameter, it is converted to float. However, if I pass it like an expression -9223372036854775807 - 1, it is correctly identified as an integer. Test script: --------------- --TEST-- Checks if the negative PHP_INT_MAX is treated as integer. --CREDITS-- Eriksen Costa <eriksen.costa@infranology.com.br> --SKIPIF-- <?php if (PHP_INT_SIZE < 8) die('64bit platforms only'); ?> --FILE-- <?php var_dump(-9223372036854775807 - 1); var_dump((PHP_INT_MAX * -1) - 1); var_dump(-9223372036854775808); ?> --EXPECT-- int(-9223372036854775808); int(-9223372036854775808); int(-9223372036854775808); Expected result: ---------------- int(-9223372036854775808); int(-9223372036854775808); int(-9223372036854775808); Actual result: -------------- int(-9223372036854775808) int(-9223372036854775808) float(-9.2233720368548E+18) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53934&edit=1
