AERN-Real

arbitrary precision real interval arithmetic http://code.google.com/p/aern/

Latest on Hackage:2011.1.0.1

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Type classes abstracting typical approximate real number arithmetic operations including rounded field operations and common elementary operations. Two kinds of rounding are supported: rounding up/down in the numerical order or rounding in/out in a refinement order.

A concrete implementation of refinement order rounded operations is given for intervals in the package AERN-Real-Interval. Concrete implementations of up/down rounded operations is given in AERN-Real-Double for ordinary Double fixed-precision numbers. These can serve as interval endpoints. In a future release also MPFR arbitrary-precision numbers will be made available as interval endpoints.

This package does not compile with ghc 7.0.* due to a compiler bug that has been fixed for the 7.2.1 release. Haddock documentation can be found via http://code.google.com/p/aern/wiki/Main.
