Primzahl erstellen mittels Crypt::Primes
am 07.02.2007 23:40:00 von werner feinHallo,
ich wollte gerade mit Crypt::Primes (auf fbsd 6.2) eine Primzahl
erstellen mit folgendem Skript:
------
#!/usr/bin/perl -w
use strict;
use warnings;
use diagnostics;
use Crypt::Primes qw(maurer);
my $primzahl = maurer(Size => 128);
print $primzahl, "\n";
-------
Allerdings kamen folgende Warnungen:
--------
Use of uninitialized value in numeric eq (==) at
/usr/local/lib/perl5/site_perl/5.8.8/Crypt/Primes.pm line 606 (#1)
(W uninitialized) An undefined value was used as if it were already
defined. It was interpreted as a "" or a 0, but maybe it was a
mistake.
To suppress this warning assign a defined value to your variables.
To help you figure out what was undefined, perl tells you what
operation
you used the undefined value in. Note, however, that perl
optimizes your
program and the operation displayed in the warning may not necessarily
appear literally in your program. For example, "that $foo" is
usually optimized into "that " . $foo, and the warning will refer to
the concatenation (.) operator, even though there is no . in your
program.

Und danach die Ausgabe .. Jetzt weiß ich nicht, wie verlaesslich ist
denn das ganze? Kann ich das einfach ignorieren?
