RE: specializations on float

the ghc docs suggest using Doubles instead of Floats because GHC specializes Double but not float...I want to use floats to save memory and to test this claim, i grepped through the libraries for the SPECIALIZE keyword and find that with the exception of a few complex routines (which I don't care about), floats are just as specialized as doubles...is this the case, or am I missing something?

I think you're right, there are just as many specialisations for Float as for Double. I've updated the docs. Cheers, Simon
