Hey all, I am working on an app where people can post items for sale.  
When they post an item, they add a price to that item.

When the item gets output to the page, it will not display the second  
number AFTER the decimal if it is a 0. If it is any other number, it  
displays fine. So, prices display as $25.0 if it ends in 0, but $25.95  
if it ends in any other number.

Here is the code in my migration to create that column in the database

t.column :price, :decimal, :precision =\> 8, :scale =\> 2, :default =\>  
0, :null =\> false

I was pretty sure that the :scale =\> 2 meant two numbers would be  
after the decimal, which seems to work fine.

I am then outputting my price in my view with this code…

$\<  
%= item.price %\>

. Also, in my form that I have to add a new  
listing, the input field for the price is being pre-populated with  
0.0. I would like to remove that as well.

Can anyone shed some light on this for me, as I appear to be missing  
something simple!

Thanks!

–Cory

Try number\_to\_currency() in your views whenever you want to display  
the amount. You can specify how many digits after the decimal point  
to show (default is 2).

Thanks Jeff, I had already figured it out using the exact helper that  
you mentioned!
