Hello Haskellers, I disliked Aeson's use of floating point numbers when JSON included decimal numbers, since I was working on a financial application. I created a version that used Decimal, but then I changed my mind and made yet another version that used Fixed. I haven't got it in a state worthy of Hackage, but you can check it out on github. https://github.com/shawjef3/aeson You can go back a commit to get the Decimal version. Enjoy! Jeff
