Synopsis

primes :: [Integer] Source #

A (lazy) list of the primes

Is this number prime? The algorithm consists of using trial division to test for very small factors, followed if necessary by the Miller-Rabin probabilistic test.

Given n, prevPrime n returns the greatest p, p < n, such that p is prime

Given n, nextPrime n returns the least p, p > n, such that p is prime
