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.


Requires: C++ compiler g++. 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.

CINT C/C++ Interpreter

CINT is a C/C++ interpreter which is aimed at processing C/C++ scripts. Scripts are programs which perform specific tasks. Generally execution time is not critical, but rapid development is. Using an interpreter the compile and link cycle is dramatically reduced facilitating rapid development. CINT covers about 95% of ANSI C and 85% of C++. CINT, written in ANSI C (about 80000 loc), is solid enough to interpret itself and let the interpreted version execute a program.

CINT makes C/C++ programming enjoyable even for part-time programmers.

CINT is developed by Masaharu Goto, who works for HP Japan. It is also integrated by the ROOT system developed at CERN to be able to execute C++ scripts and C++ command line input. CINT also provides ROOT with extensive RTTI capabilities.
