LEDA NUMBERS Package - available for Linux, Mac OS X & MS Windows

About LEDA Numbers: 

The LEDA Numbers Package is a C++ library that provides all functionality as listed in the chapter Number Types and Linear Algebra of the manual of the LEDA Software Library.

Among others it specifically provides number types  that can be used for exact computation with both Cartesian and homogeneous representations such as integers with arbitrary length, rational numbers and a real number data type. The implementation is not identical with the implementation incorporated in any of the current LEDA editions.

LEDA Numbers is fully compatible with CGAL 4.5.

LEDA number types versus LEDA Numbers Package:

On average, the types leda::integer, leda::rational and leda::real of the LEDA Numbers package are a bit faster than their counterparts in LEDA. The corresponding types of the LEDA package are used within the geometric kernel of LEDA. Replacing them with the implementation of the LEDA Numbers package would not automatically increase the speed of LEDA's geometric kernel, since the algorithms of that kernel have been specifically adapted to the number types implementation of the LEDA package.
