Traditionally, most rand()-style functions return a decimal of 0<=x<1.  Perl
gives you a bit better, giving you a rand(n) function which will return 0<=x<n.

In general, you'd probably use

        int(rand(18))

to truncate the value.  This will return a value of 0..17.  If you want 1..18,
just add one.
