Delisoft Ltd (http://www.delisoft.fi) develops C++ libraries and Microsoft
Excel
add-in libraries based on interval arithmetic. Free Evaluation Kits of 
our products listed below are available at the given WWW-sites.

C++ LIBRARIES

LIA InC++library
LIA InC++ library extends C++ standard arithmetic into extended interval
aritmetic including closed, open, infinite, complement and multi-intervals.

GIA InC++ library
GIA InC++ is a C++ library for global unconstrained optimization and
interval function evaluation based on the interval arithmetic approach. All
minimizers and maximizers can be bound down to user given precision.

ICE InC++ library
ICE InC++ is a C++ library for interval constraint solving.
ICE either bounds all solutions of a set of non-linear equations and
inequalities, or generates (bounds) individual solutions down to user given
precision.

MICROSOFT EXCEL ADD-IN LIBRARIES

Interval Calculator for Microsoft Excel
Interval Calculator is an extended interval arithmetic add-in package for
Microsoft Excel.

Interval Solver for Microsoft Excel
Interval Solver is an add-in for Microsoft Excel that makes interval
computations and constraint solving possible. The system interprets Excel
formulas as a set of equations and inequalities. Interval Solver can either
bound all solutions of the
equations and inequalities, or generate (bound) individual solutions down
to user given precision.
