* PHP-7.0:
Fix bug #73190: memcpy negative parameter _bc_new_num_ex
(cherry picked from commit af1bf873fe)
This is bcmath, a library of arbitrary precision math routines. These routines, in a different form, are the routines that to the arbitrary precision calculations for GNU bc and GNU dc. This library is provided to make these routines useful in a larger context with less restrictions on the use of them. These routines do not duplicate functionality of the GNU gmp library. gmp is similar, but the actual computation is different.
