# all my bigdeciamls going into this have been .round(2) beforehand

dollar[1] = dollar[1].split[1]
dollar[1] = "#{dollar[1][0, dollar[1].length-2].gsub(/(\d)(?=(\d\d\d)+(?!\d))/, "\\1,")}.#{dollar[1][dollar[1].length-2,2]}"

# credit where credit is due, I stole the gsub part from merb numeric helper - thanks merb!!
# the rest was bigdecimal docs :)
