Derick ------------------------------------------------------------------------ [2003-05-15 07:33:45] derick@php.net Found the problem... the float (internally) reaches maximum precision in the case. Going to try to fix it in some way. ------------------------------------------------------------------------ [2003-05-09 09:22:00] jaakkoho at paju dot oulu dot fi Both the following commands outputs same value: base_convert("aaaaaaaaaaa", 36, 10); base_convert("aaaaaaaaaab", 36, 10); output: 37606201097790608 In fact, the last character can be whatever between 0-z, and the output is always same. This bug appears only if strlen($string_to_convert) > 10. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23564&edit=1
