Hi all,

GMP '0' object does not evaluated as empty()

$ ./php-bin -r '$v = gmp_init("0"); var_dump(empty($v), $v == 0);'
bool(false)
bool(true)

This may cause confusion and bugs in user scripts.

Most math functions does not work with GMP object neither.
We might be better to raise warning for math functions that
do not support GMP object.

Regards,
