This module supplies default instances for the real number classes defined in Data.Number.ER.Real.Approx.
These classes express loosely coupled abstraction layers. To preserve the intended loose coupling, please use these definitions only in functions that do not import or export any real numbers or real functions.
Limited granularity, but sometimes up to 100x faster than ERFloat!
