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.

Description:
------------
If you pass to base_convert a numeric string like "0.5", to have it converted
from base 10 to base 16, PHP will interpret the input as decimal 5 and return
hexadecimal 5. 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
