Bug #65212 [Com]: problem if pass in numeric string containing a float between 0 and 1

Edit report at https://bugs.php.net/bug.php?id=65212&edit=1 ID: 65212 Comment by: iam4webwork at hotmail dot com Reported by: iam4webwork at hotmail dot com Summary: problem if pass in numeric string containing a float between 0 and 1 Status: Open Type: Bug Package: Math related Operating System: Irrelevant PHP Version: Irrelevant Block user comment: N Private report: N New Comment: _php_math_basetozval appears to be source of problem b/c while it mimics strtol, unlike strtol it fails to adequately deal with '.' being an illegal character. strtol disregards '.' and all subsequent input whereas _php_math_basetozval just skips the '.' and processes the next character.

I suspect that the problem lies internally in the logic of _php_math_basetozval. Test script: --------------- var_dump(base_convert("0.5",10,16)); Expected result: ---------------- I expected PHP to return a zero just as printf("%x","0.5") and dexhex() do. Actual result: -------------- 5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65212&edit=1
