Rails money round cents up

I'm trying to round my money without cents, but I want the amount to be rounded up always (ceil).

I've done:

MoneyRails.configure do |config|
  config.rounding_mode = BigDecimal::ROUND_CEILING
end

Money.new(12345).format(:no_cents)

But it still returns "$123" instead of "$124".

I'm looking through the Money gem and format doesn't appear to leverage any rounding rules. Its just chopping off cents to get an "absolute" value.

formatted = self.abs.to_s
...
if rules[:no_cents] || (rules[:no_cents_if_whole] && cents % currency.subunit_to_unit == 0)
  formatted = "#{formatted.to_i}"
end

Tried to find a work around for you, maybe add this as a method to your Rails Model:

[2] pry(main)> require 'money'
=> true
[3] pry(main)> money = Money.new(12345, 'USD')
=> #<Money fractional:12345 currency:USD>
[6] pry(main)> "#{money.currency.symbol}#{money.to_f.ceil}"
=> "$124"

Have you tried setting the rounding mode to ROUND_UP, rather than ROUND_CEILING?
