Perl: Need to create random binary codes in a script

Hi everyone. Beautiful rainy day where I am.

I am able to create semi-random numbers like 4404315944, but I feel the need to create random binary numbers in a perl script.

Does anyone know how to translate any number, even if it's long like 4404315944?

I read something about ("%b",$number); but that doesn't work in a script.

Thank you very much for any help.

Best regards,

Depends on your definition of binary.

printf("%b",123);

will output

1111011

ie:  base 2

How do you put that into a string?

Thank you very much.

dr34m3rs.

you should use sprintf *not* printf, ie:

$str = sprintf("%b",$number);
