Rails: Is there a rails trick to adding commas to large numbers?

ruby, ruby-on-rails

Solution

You want the `number_with_delimiter` method. For example:

<%= number_with_delimiter(@number, :delimiter => ',') %>

Alternatively, you can use the `number_with_precision` method to ensure that the number is always displayed with two decimal places of precision:

<%= number_with_precision(@number, :precision => 2, :delimiter => ',') %>

Problem

Is there a way to have rails print out a number with commas in it? For example, if I have a number 54000000.34, I can run <%= number.function %>, which would print out "54,000,000.34" thanks!
