What is Sollya?
Sollya is both a tool environment and a library for safe floating-point code
development. It is particularily targeted to the automatized
implementation of mathematical floating-point libraries
libm). Amongst other features, it
offers a certified
infinity (supremum) norm and a fast Remez algorithm.
Sollya is developed
by PEQUAN and APICS.
It is written by Christoph Lauter,
M. Joldeș and N. Jourdan. The Inria project-teams Arénaire and Caramel contributed to previous versions of Sollya.
Sollya provides you with:
- a certified infinity (supremum) norm for computing safe approximation error bounds,
- an automatized implementer for approximation polynomials in CRlibm-style C-code with the corresponding Gappa proof,
- a fast implementation of Remez algorithm for computing minimax polynomials,
- a full-featured programming language adapted to analysis of numerical programs like in a Computer-Algebra-System,
- a faithful-rounding, multi-precision evaluator of composed functional expressions extending MPFR,
- a highly accurate and fast floating-point infinity (supremum) norm,
- support for floating-point rounding operators and expansions in common precisions,
- a special floating-point minimax procedure,
- basic MathML input and output support,
- interfaces for extending Sollya with your own code and much more...
In order to build Sollya, you will need: a C compiler (e.g., gcc
), a C++ compiler (e.g., g++
, and libxml2
is highly recommended for using the plot and externalplot commands. It is not required though.
History: the list of all versions of Sollya is available here.
A snapshot of the Sollya git repository is usually taken every Sunday. It is as easy to install as a stable release!
