Clears (sets to 0) bit index in
num. The index starts at 0.
Parameters
num
A GMP object.
index
The index of the bit to clear. Index 0 represents the least significant bit.
Return Values
A GMP object.
Examples
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 above example will output:
254
Notes
Note:
Unlike most of the other GMP functions, gmp_clrbit
must be called with a GMP object that already exists (using
gmp_init for example). One will not be
automatically created.
