#2759: Data.Generics.ConstrRep isn't general enough

---------------------------------+------------------------------------------
The type ConstrRep in Data.Generics is used to represent constructors for
types.
The FloatConstr constructor is the one used for all kinds of floating
point primitives.
But FloatConstr has an argument of type Double. This limits the primitive
floating point types to those that are accurately representable as a
Double.
In other places in Haskell where an accurate and generic floating point
value is needed the type Rational is used. It should be used here too.
