About:
CLN (Class Library for Numbers) is an efficient C++ library for numbers, supporting arbitrary precision integers, rationals, and floats. It provides a comprehensive set of arithmetic operations and functions, making it a robust foundation for mathematical applications. Its design prioritizes speed and memory efficiency, often outperforming other bignum libraries.

Key Features:

Arbitrary precision arithmetic
C++ interface with operator overloading
Efficient memory management and speed
Support for complex numbers and transcendental functions

Use Cases:

Developing computer algebra systems
Scientific and engineering calculations requiring high precision
Cryptographic algorithm implementation

Alternatives:

GMP (GNU Multiple Precision Arithmetic Library) – CLN is built on top of GMP but provides a more convenient C++ object-oriented interface, whereas GMP is a C library.
MPFR – CLN includes floating-point support but is broader in scope; MPFR is specialized for correctly rounded floating-point arithmetic.
