Can I change the class of an element that Ruby's Pluck returns

I am familiarizing myself with the data in a database I inherited. And the credit_amount field is a decimal which when pretty printed returns something that looks like this:

<BigDecimal:6d28088,'0.0',9(18)>

I want to be able to read it, after I get the info using pluck and then group_by like this:

emails = Customer.pluck(:shop_id, :customer_id, :email, :credit_amount )
gemails = emails.group_by{ |shop_id, customer_id, email, credit_amount| customer_id }
pp gemails

Currently when this prints it looks like this:

 "21274984473"=>
  [[105,
    "21274984473",
    "[email protected]",
    Mon, 28 Aug 2017 16:39:28 UTC +00:00,
    #<BigDecimal:6d28088,'0.0',9(18)>],
   [105,
    "21274984473",
    "[email protected]",
    Wed, 02 Aug 2017 20:09:37 UTC +00:00,
    #<BigDecimal:a0e1690,'0.0',9(18)>]],

Just trying to read that BigDecimal number.. using to_f has worked in the past, just not sure where to put that here?

Thanks

You could try this:

emails.each { |e| e[-1] = e[-1].to_f }
