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

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

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.

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:

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 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).

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.
