AR validates_uniqueness_of floats and find_by_FLOAT_FIELD

Any further news on this? I tried today on Rails 2.3.5 and got the following query by doing a Place.find_by_lat

SELECT * FROM "places" WHERE ("places"."lat" = '45.3243')

To me, this is expected behavior.

Like Ryan, I was unable to duplicate this issue with Rails 2.3.5:

➜  code  rails -v
Rails 2.3.5
➜  code  rails validates_uniqueness_of_float
...
➜  code  cd validates_uniqueness_of_float 
➜  validates_uniqueness_of_float  script/generate model place lat:float
...
➜  validates_uniqueness_of_float  rake db:migrate
(in /Users/dtrasbo/code/validates_uniqueness_of_float)
...
➜  validates_uniqueness_of_float  script/console 
Loading development environment (Rails 2.3.5)

ruby-1.8.7-p249 > Place.create!(:lat => '42.123')

ruby-1.8.7-p249 > Place.find_by_lat(42.123)

class Place < ActiveRecord::Base
  validates_uniqueness_of :lat
end
