So this has been a while, but i think that decodeFloat, incrementing the mantissa, encodeFloat might work. But then again, it might not. :)

My preference would be for succ (+-0) to return the smallest positive real, since then you could define succ x to be the unique y with x < y and forall z . z < y => not (x < z), where such a y exists, and I'm not sure if the Haskell standard knows about signed zeros.
Is this really useful? Why would you need this number? Peano artithmetic on reals? :-)
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.
