cln: CLN (Class Library for Numbers) cln: cln: CLN is a library for computations with all kinds of numbers. It has a cln: rich set of number classes: Integers (with unlimited precision), cln: rational numbers, floating-point numbers, short float, single float, cln: double float, long float (with unlimited precision), complex numbers, cln: modular integers (integers modulo a fixed integer), univariate cln: polynomials. CLN is memory efficient. CLN is speed efficient. cln: cln: cln:
