similar to: BigDecimal to letters

I was just playing around in irb and noticed that while BigDecimal + Integer => BigDecimal, BigDecimal + Float => Float. Is there any reason for this? It seems inconsistent and means you have to check the class of any number you add to a BigDecimal, which looks very un-Ruby-like to me. Ashley

So, I''m personally cool with this change (patch from #5454, applied in [4596]), and I''ll make it work for Oracle tomorrow. But just wondering if folks considered the performance impact of the change? From a simple test it seems that BigDecimal math is about twice as slow as using Floats.

I have a strange problem with my setup of Passenger and Ruby Enterprise Edition. Sometimes the loading of BigDecimals from the database and session fails (silently) and the variable containing the BigDecimal is just empty. I cannot pinpoint where/when/how it happens, and it IS only periodic. I am using the newest versions of both Passenger and REE - I have even tried to run with latest commit

I need to do some precise math, going to 12-14 decimal places, so I''m using BigDecimal. How can I store this in a db? I''m using postgresql 8.1.0, if that matters at all. I found a plugin [1] but it gives me the error "You have a nil object when you didn''t expect it! The error occurred while evaluating nil.each_pair," with no line number. The plugin itself

I was hoping 1.1 would provide a way to map SQL "decimal" column types to BigDecimal values, since BigDecimal is part of the Ruby standard api as of 1.8. But I don''t see any support for that in the migration documentation, and when I try to let Active Record do the mapping for me, it seems to coerce the column into a Float (as the AwdwR book says). Is it really there in

Hi all, I''m working on a financial app, and have set up some columns in my tables as decimals with precision => 8 and scale => 2. My migration looks like: change_column :lineitems, :price, :decimal, :precision => 8, :scale => 2 change_column :payments, :amount, :decimal, :precision => 8, :scale => 2 I''ve run the migration and restarted the server. I

I definitely need to use RJS templates for my current application. I''ve used Google for the past twenty minutes or so, yet I can''t find a good resource that will get me started and show me what the page object can do. Any links? When an Ajax link is clicked, I''m trying to change the background of a "primary" list item, as well as the background and text of

What''s a rule of thumb for guesstimating how many Mongrels to use in a cluster for an app? I have an app that gets about 5000 unique visitors per day. I figured I''d give it plenty of Mongrels -- twenty to be specific. After running out of memory and hitting the swap periodically, I scaled it back to five and it still seems to serve up visitors fine. So, is there some super-secret

Ok so I have this route map.namespace :trades do |trades| trades.resources :buys, :path_prefix => ''/trades/:contract_id'' end I want the contract_id variable to filter a list of buys then I try to open this route http://localhost:3000/trades/1/buys I get a strange error: ActionController::RoutingError in Trades/buys#index Showing trades/buys/index.html.erb where line

There''s a test for activerecord called test_numeric_fields in base_test.rb. here''s the test def test_numeric_fields m = NumericData.new( :bank_balance => 1586.43, :big_bank_balance => BigDecimal("1000234000567.95"), :world_population => 6000000000, :my_house_population => 3 ) assert m.save m1 =

Folks: I''ve uplaoded the B1.05 version of AWDwR. It fixes a number of reported errata (and a few that weren''t reported :), and adds two significant changes: 1. It now uses the new Active Record decimal -> BigDecimal conversion. I''ve personally been waiting for this for a long time, and I''m really happy it''s now part of core. However,

Hi, I was wondering if it is possible to output validation errors in a nested form? I suppose this should be possible, but I am experiencing an error message that I can''t track down. The error I get is the following : TypeError in Store/orders#create Showing app/views/store/orders/new.html.erb where line #45 raised: can''t convert Array into String This is ocurring in the

Hello How can I test equality with two objects when they include some attribute that is BigDecimal? if I make something like this: it "should ...whatever" do obj = Factory.create(:my_object) ... MyObject.first.should == obj end. FAILS This fails because the object expected is different from the object gotten, and the only difference are the BigDecimal attributes, that are

I''ve created a plugin that lets you spell out numbers (under one thousand, in English, for now). Examples: >> 23.spell => "twenty-three" >> 23.spell :noun => ''person'' => "twenty-three people" >> (23.14).spell_currency => "twenty-three dollars and fourteen cents" >>

Hello, I'm in the early stages of designing an Emergency calling service IVR application. The IVR application asks simple one or two questions like "which is the postal code of the area you are currently calling from ?" "Is the correct ?". The expected values are a 5-digits number like "twenty-five-thousand-two-hundreds-twelve" or

Hi, Why does ActiveRecord allow perception of success when updating an ID, however it doesn''t really work(i.e. no change in database)? Here''s an example. The update of "id" versus update of a non-existent attribute. ?> ai = AccountItem.find(:first) => #<AccountItem id: 1, account_id: 1, date: "2009-01-11", amount:

Hi, What do you guys use to definitely handle decimal numbers? This is getting me crazy!
