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 ...
Integer division; Efficient integer division and calculating of the remainder when the divisor is known; Integer square and cube roots; Unusual number systems, including base −2; Transfer of values between floating-point and integer; Cyclic redundancy checks, error-correcting codes and Gray codes; Hilbert curves, including a discussion of ...
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.
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 ...
Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
For uneven number of terms in the generator polynomial there can be a period of ; however, these generator polynomials (with odd number of terms) do not discover all odd number of errors, so they should be avoided. A list of the corresponding generators with even number of terms can be found in the link mentioned at the beginning of this section.

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.
