Class Library for Numbers (CLN) is a library for computations with all kinds of numbers. Its rich set of number classes includes integers, rational numbers, floating-point numbers, complex numbers, modular integers, and univariate polynomials. It implements elementary functions (also with unlimited precision), logical functions, and transcendental functions. It is designed for memory and speed efficiency as well as interoperability. License: GNU General Public License (GPL) Changes: Large amounts of memory in computation of some functions and constants are now saved. Support for huge numbers was added. C++ exceptions are now used for error handling. The cln-config script was replaced by a pkg-config implementation. A bug when comparing Z/2Z ring zeros and a few build problems were resolved.
