CLN Class Library for Numbers

CLN is a library for efficient computations with all kinds of numbers in arbitrary precision. It is distributed under the terms and conditions of the GNU General Public License.

Features:

Requires: C++-11 compiler. The following C++ features are used: classes, member functions, overloading of functions and operators, constructors and destructors, inline, const, multiple inheritance, templates, namespaces, and exceptions. The following C++ features are not used: new, delete, virtual inheritance.

CLN is available from https://www.ginac.de/CLN/.
