GHC.Float.RealFracMethods
Description
Methods for the RealFrac instances for Float and Double,
with specialised versions for Int.
Moved to their own module to not bloat GHC.Float further.
The API of this module is unstable and not meant to be consumed by the general public.
If you absolutely must depend on it, make sure to use a tight upper
bound, e.g., base < 4.X rather than base < 5, because the interface can
change rapidly without much warning.
