history
Project history and usage
CLN, the Class Library for Numbers, is a C++ library for arbitrary-precision integers, rationals, floats, complex numbers, modular integers, and univariate polynomials.
Project history
CLN was written by Bruno Haible and is maintained by Richard B. Kreckel. The manual copyright history reaches back to Haible's 1988 work, and the official NEWS file records public 1.0-era releases beginning in January 1999.
The library was designed around efficient numeric computation in C++: immediate small numbers, garbage collection, assembly kernels on selected CPUs, optional GMP low-level routines, Karatsuba multiplication, very-large-number algorithms, and binary splitting.
Adoption history
CLN is closely associated with GiNaC, whose website lists CLN as related software and whose symbolic-computation focus explains why an arbitrary-precision numeric substrate mattered. CLN's own manual notes that its numeric subtypes match Common Lisp number types, so CLN can serve Common Lisp implementations as well as C++ mathematical software.
The official CLN page points users to Debian, Fedora, openSUSE, and other distribution packages, while the batch input records packaging across Alpine, Homebrew, Debian/Ubuntu as `libcln-dev`, Fedora, MacPorts, Nix, Arch, Winget, and openSUSE.
How it is used
Developers link CLN into C++ programs that need arbitrary-precision numeric types with algebraic operator syntax. The manual documents building with a C++11 compiler, optional GMP support, namespace `cln`, and integration hooks for memory allocation and exceptions.
The Homebrew package exposes the sample `pi` executable, but CLN's primary value is as a development library rather than an end-user CLI.
Why package nerds care
CLN matters to package maintainers because it is a compiled C++ numeric library with ABI, compiler, architecture, and GMP concerns. The NEWS history repeatedly calls out portability fixes for CPU architectures, GCC versions, MinGW, ARM, AArch64, MIPS64, RISC-V, LoongArch, and cross-compilation.
Its 1.1.0 move into namespace `cln`, separate headers, and dependence on installed GMP version 3 or newer are classic downstream packaging events: they changed include paths, source compatibility, and dependency expectations.
Timeline
- 1988: Manual copyright history begins with Bruno Haible's work.
- 1999: CLN 1.0 released.
- 2000: CLN 1.1.0 moves identifiers into namespace `cln` and relies on installed GMP.
- 2008: CLN 1.2.0 adds huge-number support and C++ exceptions.
- 2009: CLN 1.3.0 switches to GNU autotools.
- 2019: CLN 1.3.5 adds build support for 64-bit MinGW, Elbrus 2000, RISC-V64, and MIPS release 6.
- 2024: CLN 1.3.7 adds LoongArch support and ARM compilation fixes.
- 2026: Official Codeberg repository metadata is created for ginac/cln.
