Yes, there is.  I'm sure that there's a module in the RAA for this,
although I can't find it at the moment.  It's not too hard to do manually,
though:

irb(main):001:0> balance = 2111000.5756
=> 2111000.5756
irb(main):002:0>  balance = (balance * 100).round/100.0
=> 2111000.58
irb(main):003:0> balance.to_s.reverse.gsub(/\d{3}/, '\&,').reverse
=> "2,111,000.58"
