Subject: [Caml-announce] exact real arithmetic
Date: Fri, 2 Nov 2001 11:32:02 +0100 (MET)	[thread overview]
Message-ID: <15330.30242.865717.221157@pc803> (raw)


This is to announce an  exact real arithmetic module for ocaml, called
Creal (for Constructive Reals). It is available from here:

      http://www.lri.fr/~filliatr/software.en.html

This module provides  an abstract data type of  real numbers, on which
all operations are exact,  and return immediately. When necessary, one
can ask for an approximation of a real number to a given precision and
this triggers all the actual computations, including approximations of
some operands to higher precisions if necessary.

This implementation  is based  on Valérie Ménissier-Morain  PhD thesis
(http://www-calfor.lip6.fr/~vmm/arith_english.html)

The tarball  includes an ocaml  interface to GMP (GNU  Multi Precision
library), mainly written by David Monniaux.

Comments and suggestions are welcome.
