BigDecimal + Float => Float?
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.

Decimals are being converted to Bigdecimals!!!!!
Hi all,
I''m working on a financial app, and have set up some columns in my

Testing equality
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

Why does ActiveRecord allow perception of success when updating an ID, however it doesn't really work(i.e. no change in database)?
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.

BigDecimal column type?
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

Ruby EE: Problem with BigDecimal
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

Float -> BigDecimal
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.

Storing BigDecimal in the db
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

the error "You have a nil object when you didn''t expect it! The error

Financial app - decimal to float conversion problem
I''m having problems with using Rails for a financial application: the
database stores financial fields as decimal, but ActiveRecord converts
these to float - so I get the rounding errors you''d expect

Decimal numbers pain
Hi,
What do you guys use to definitely handle decimal numbers? This is
getting me crazy!
I use BigDecimal, but it craps out of the input number is something like
"14,53", Rails transforms it as 14.0
Any solution?
