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 ...
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.
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 ...
Code fragment 1: Simple polynomial division. Note that this example code avoids the need to specify a bit-ordering convention by not using bytes; the input bitString is already in the form of a bit array, and the remainderPolynomial is manipulated in terms of polynomial operations; the multiplication by could be a left or right shift, and 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 ...

For degrees up to 32 there is an optimal generator polynomial with that degree and even number of terms; in this case the period mentioned above is . For n = 16 {\displaystyle n=16} this means that blocks of 32,767 bits length do not contain undiscovered 2-bit errors.
