It is available at <a href="http://www.mpfr.org/">http://www.mpfr.org/</a>. The library is remarkable for the care taken to return correctly rounded results. It is hoped that this will form a good base for experimentation with algebraic algorithms that mix symbolic and numeric techniques.</p> </div> </div> </body> </html>
