And during this conversion, some lower digits may be lost due to the precision of the double value, which depends on the platform. http://www.php.net/manual/en/language.types.float.php ------------------------------------------------------------------------ [2003-05-09 08:37:03] jaakkoho at paju dot oulu dot fi Converting a decimal to n-base and then back to decimal failed: print base_convert(base_convert("10000000000000001", 10, 36), 36, 10); output: 10000000000000000 (the last '0' should be '1') Bug appears only if strlen($value_to_convert) > 16. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23563&edit=1
