Just a quick question, how does Perl interpret something like
$array[0.7995038473872]?

Just like $array[ int(0.7995038473872) ], i.e. the floating point number is coerced into an integer value by cutting off the decimal places.

Ah cool. So when using rand in this aspect (i.e. getting random indexes from an array), the int is negligible?

Thanks Thomas!
