Try your attempt with 17 and 19...

I do. Since there aren't enough digits, Math::BigFloat to the rescue:

#!/usr/bin/perl
use Math::BigFloat;
Math::BigFloat->div_scale(50);
my @values = map {
        my $i = Math::BigFloat->new( 1 );
        scalar $i->bdiv( $_ );
} (2,3,6,7,9,11,13,14,17,19,23);

for (@values) {
    /\.\d*?(\d+?)\1/;
    print "$_: $1\n"
}
__END__

The regex is the same, though. Still missing something?

update: Oh, I see. "try with 170..." :-)

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
