gmp_com — Calculates one's complement
num
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
Returns the one's complement of num, as a GMP number.
Example #1 gmp_com() example
<?php
$com = gmp_com("1234");
echo gmp_strval($com) . "\n";
?>The above example will output:
-1235
