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.
Note:
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.
Example 1. gmp_clrbit() example <?php
$a = gmp_init("0xff");
gmp_clrbit($a, 0); // index starts at 0, least significant bit
echo gmp_strval($a) . "\n";
?> |
The printout of the above program will be:
