Math::RandomOrg - Retrieve random numbers and data from random.org.
use Math::RandomOrg qw(randnum randbyte);
my $number = randnum(0, 10);
my $octet = randbyte(1);
Math::RandomOrg provides functions for retrieving random data from the
random.org server. Data may be retrieved in an integer or byte-stream format
using the "randnum" and
"randbyte" functions respectively.
- Carp
- Exporter
- Math::BigInt
- LWP::Simple
None by default. You may request the following symbols be exported:
- "checkbuf()"
- This routine takes no parameters and simply returns a single value (e.g.,
"28%") telling you how full the buffer
is. At 100%, the buffer is full and you are free to hit it with automated
clients. At 0%, the buffer is empty and requests will hang. When less than
100%, the buffer is being filled continually, but doing so takes time. I
advise people with automated clients to check the buffer level every once
in a while and only issue requests when the buffer level is 20% or
higher.
- "randnum ( $min, $max )"
- Return an integer (specifically a Math::BigInt object) between the bounds
[ $min, $max ]
(inclusive).
By default, $max and
$min are positive and negative 1e9,
respectively. These default values represent random.org's current
extrema for the bounds of the randnum function. Therefore,
$min and $max may not
exceed the default values.
- "randbyte ( $length )"
- Returns an octet-string of specified length (defaults to one byte), which
contains random bytes.
$length may not exceed 16,384, as this
is the maximum number of bytes retrievable from the random.org server in
one request, and making multiple requests for an unbounded amount of
data would unfairly tax the random.org server. If you need large amounts
of random data, you may wish to try the Math::TrulyRandom module.
- "randseq ( $min, $max )"
- The randseq script returns a randomized sequence of numbers. This
corresponds to dropping a number of lottery tickets into a hat and drawing
them out in random order. Hence, each number in a randomized sequence
occurs exactly once.
Example: "randseq(1, 10)"
will return the numbers between 1 and 10 (both inclusive) in a random
order.
