Adding commas to a number

Question

I\'m trying to make a number like 1234567 go to be 1,234,567, but need some help. My thoughts were that I could use a split with \\d{3} and then join a , to that. T

Answer 1

I'd use Rails' ActiveSupport (even if I wasn't using Rails for the actual application), which also formats it properly for the current locale. If you aren't already using Rails, you'll need to install the gem:

gem install activesupport

Then, require it like this:

require "active_support/core_ext"

Then you can do:

=> ActiveSupport::NumberHelper.number_to_delimited(1234567)
=> "1,234,567"
