number_to_currency(101.00) returns $110

From a view:

<%= number_to_currency(101.00) %>

outputs: $101.00

...and from the console:

foo = ActionView::Base.new
foo.extend ActionView::Helpers::NumberHelper
foo.number_to_currency(101.00)
=> "$101.00"

Tested Rails "3.0.0.beta3"

Are you passing in any additional parameters to number_to_currency?

I'm not passing anything else. Tried from the console, and mine fails with $110.00. Are you running the gem version of Rails 3 Beta 3 perhaps?

Mike, can you give pastie of your console showing it is failing along with Ruby version you are using.

I tested it with rails3 edge. And this is the result I got in console.

=> "$101.00"

Here is my Gemfile. Perhaps it is something here that is conflicting.

You might want to go through and comment out gem by gem in your Gemfile to see if any are causing this issue.

Yes, first you should try with a fresh application and if all is working could be a bug related with one of the plugins you are using.

As far as I can tell, it's in BigDecimal.

Hi Kim,

Yeah, it looks like BigDecimal is doing something funky. I have the same version and patchlevel and same result as you.

The last update to Snow Leopard (10.6.3) shipped with a version of ruby 1.8.7 with a known bug in BigDecimal. Apple really dropped the ball on this one - the fixed version has been available since June 2009.

One more reason to use RVM.
