gmp_clrbit
(PHP 4 >= 4.0.4, PHP 5) gmp_clrbit -- Clear bit
Descriptionvoid gmp_clrbit ( resource &a, int index ) Clears (sets to 0) bit index in
a. The index starts at 0.
Замечание:
Unlike most of the other GMP functions, gmp_clrbit()
must be called with a GMP resource that already exists (using
gmp_init() for example). One will not be
automatically created.
