Is there any way to do this (yet)? I found a case where I really need: f :: Float -> Float where f x is the least y such that x < y even if i have to FFI to C, I'd really like a solution. any help would be appreciated. - Hal _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
