[racket] 80-bit precision in Racket

Marc,

> If performance is important, have you considered using Gambit instead?  It generates very good floating point code and it should not be too hard to extend it to handle 80 bit floats.

Yes performance is important, but we also need Racket's
superb DSL creation feature
(http://docs.racket-lang.org/guide/languages.html).
That was actually the reason we chose Racket some while ago.

Best regards,
