The arc4random family of random number functions are not defined in POSIX standard, but is found in some common libc implementations. It used to refer to the keystream generator of a leaked version of RC4 cipher (hence " a lleged RC4 "), but different algorithms, usually from other ciphers like ChaCha20 , have been implemented since using the ...
isl (integer set library) is a portable C library for manipulating sets and relations of integer points bounded by linear constraints. [2] The following operations are supported: [3] intersection, union, set difference; emptiness check; convex hull (integer) affine hull; integer projection; computing the lexicographic minimum using parametric ...
In computer science, a generator is a routine that can be used to control the iteration behaviour of a loop. All generators are also iterators. [1] A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values.

Given an integer a and a non-zero integer d, it can be shown that there exist unique integers q and r, such that a = qd + r and 0 ≤ r < | d |. The number q is called the quotient, while r is called the remainder. (For a proof of this result, see Euclidean division. For algorithms describing how to calculate the remainder, see Division algorithm.)
Let R be a ring.. R is a free module of rank one over itself (either as a left or right module); any unit element is a basis.; More generally, If R is commutative, a nonzero ideal I of R is free if and only if it is a principal ideal generated by a nonzerodivisor, with a generator being a basis.

The basic interface is for C, but wrappers exist for other languages, including Ada, C++, C#, Julia, .NET, OCaml, Perl, PHP, Python, R, Ruby, and Rust. Prior to 2008, Kaffe, a Java virtual machine, used GMP to support Java built-in arbitrary precision arithmetic. [7] Shortly after, GMP support was added to GNU Classpath. [8]
