Features:

- Rich set of number classes: Integer (unlimited precision), rational, short float, single float, double float, long float (unlimited precision), complex, modular integer, univariate polynomial.
- Elementary, logical, transcendental functions.
- C++ as implementation language brings
- efficiency,
- type safety,
- algebraic syntax.

- Memory efficiency:
- Small integers and short floats are immediate, not heap allocated.
- Automatic, non-interruptive garbage collection.

- Speed efficiency:
- Assembly language kernel for some CPUs,
- Karatsuba and Schönhage-Strassen multiplication.
- binary splitting.

- Interoperability:
- Garbage collection with no burden on the main application,
- hooks for memory allocation and exceptions.

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.

CLN is available via anonymous ftp from `ftp://ftpthep.physik-uni-mainz.de/pub/gnu/`.

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.
