[Haskell-cafe] Just for a laugh...

[Andrew Coppin]

If you're bored... can you come up with a solution to this?

(Obviously a pretty silly challenge, but hey.)


My first instinct was to use Data.Bits - but I see no instance for 
Double. (Presumably because performing bitwise operations on a Double is 
a pretty odd thing to want to do.) So my next guess is to do some 
bizzare type system hackery that allows you to transform a Double 
into... whichever integer type is the same size, and proceed from there. 
Does anybody know how to do that?

(Otherwise... wasn't there some library somewhere for serialising values 
in binary?)
