@hackage AERN-Real-Interval2011.1

A concrete implementation for the refinement-order type classes from AERN-Real in the form of interval arithmetic. The arithmetic supports also anti-consistent intervals (ie [l,r] with l >= r) and maintains monotonicity in the refinement order so that both inner and outer approximations of exact interval expressions can be safely computed.

The package AERN-Real-Double makes it possible to use ordinary machine Double values as endpoints, although limited to its fixed granularity (ie precision).

A package AERN-Real-MPFR will be provided in future to facilitate (via package hmpfr) the use of the MPFR arbitrary granularity (ie precision) floating point numbers as endpoints.
