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.

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.

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

Mapping to BigDecimals instead of Floats
Hi everyone,
I''m new to Rails and Ruby, and have been working my way through the Pickaxe
and Agile Rails books for the last week or so. With a background in payroll
apps I found that the default ActiveRecord mapping of decimal columns to
float variables really bothered me! Financial calcs need high levels of
accuracy and floats just don''t give you that.

Changing column to NOT NULL with migration silently failing.
Hi
I''ve created a migration called
make_customer_type_id_not_null_for_customers. The migration .rb file
looks like this:

def self.up
change_column(:customers, :customer_type_id, :integer, { :null => false })
end

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

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

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

Migration, BigInts, and string lengths
Howdy Y''all,
I was thrilled to recently discover migrations, as that framework
addresses a common problem in an elegant way. I have, however, gotten
tripped up a bit as I''ve worked with them.
The first problem I encountered was that, though I was using a BigInt
data type in a field in my dev database, my unit tests were failing
because when I copied the schema from the dev

Typecast values on change_column for postgresql
Hello,
Currently if you have a string column that have only number values (think a
year column using string by mistake) and you want to change to integer, you
can''t.
If you apply this monkey-patch will be possible:
https://gist.github.com/1393441
Note: if some value can''t be casted by postgresql (if have a letter for
example), the migration will fail as expected.

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.

saving money as decimals now ok?
Now that Rails core converts a database''s decimal type into a Ruby
BigDecimal type, is it ok to now store money information as a decimal

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?
