Subject: Integer/Float oddity

not really an oddity, more a lack of understanding on my part regarding
ruby's internal type conversion...

(100*(1.15-1))
=> 15.0

(100*(1.15-1)).to_int
=> 14

(100*(1.15-1)).to_int.round
=> 15

15.0.to_int
=> 15

what am i missing here?  i never would have thought to use .round to
get the 'correct' result unless someone told me.  by correct i mean if
i was doing this with a paper and pencil, i would expect to get 15, not
14.

any insight would be appreciated, especially a way (if possible) to
override this behaviour so i dont run into this in the future.

thanks,
