Hi,

I have a question about displaying digits in Rails.

whenever I print the price of an item, if the last digit is a zero or  
double zeros then it doesn’t display properly.

How do I display a number so that it looks like currency?

thank you!

There are some helpers that may be useful:

```
 number_to_currency
 number_with_delimiter
 number_with_precision

```

See [http://api.rubyonrails.org](http://api.rubyonrails.org) for detais.

Oops. That second example should be

\<%= number\_with\_precision(number, 2) %\>

Like this:

\<%=h money(number) %\>

Of course “number” will be the name of YOUR field.  
Or you can do this:

\<% number\_with\_precision(number, 2) %\>

where 2 is the number of digits of the fraction to show.
