Salut Rémi, I was being a bit provocative by saying it was "FUD", sorry ;-) Thanks a lot for showing how Groovy performed when using doubles instead -- ie. comparing the same thing for all those languages. Using BigD by default is a very old decision we made (as I briefly explained in the comments of your post), and is not something we can easily come back on. Nor do we have the intention to come back on it, as (oddly as it may sound) it's been an aspect of Groovy that make it a great sell to financial institutions! (insurance companies, banks, hedge funds managements, trader and bank software vendors, etc.)
