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.
Set machine floating point unit to the upwards-directed rounding mode.
This procedure has to be executed before using
as a basis for interval and polynomial arithmetic defined in this package.
Limited granularity, but sometimes up to 100x faster than ERFloat!
