GMP **gmp_random** int $limiter

Generate a random number. The number will be between 0 and (2 ** n) - 1, where n is the number of bits per limb multiplied by . If is negative, negative numbers are generated. limiter``limiter

A limb is an internal GMP mechanism. The number of bits in a limb is not static, and can vary from system to system. Generally, the number of bits in a limb is either 32 or 64, but this is not guaranteed.

A random GMP number.

Voorbeeld: example

<?php
$rand1 = gmp_random(1); // random number from 0 to 1 * bits per limb
$rand2 = gmp_random(2); // random number from 0 to 2 * bits per limb

echo gmp_strval($rand1) . "\n";
echo gmp_strval($rand2) . "\n";
?>
