We have been able to speed things up a bit. Going further, we have discussed more methods for determining if a number is prime and also determining the next highest prime. To recap, we have determined that the Baillie-PSW primality test is much faster than the Miller-Rabin. This is due...
def eratosthenes(maximum: int) -> list[int | None]: """ Find all the prime numbers between 2 and `maximum`. Args: maximum: The maximum number to check. Returns: A list of primes between 2 and `maximum`. """ if maximum < 2: return [] # Discard even numbers by default. sequence...
I dont know how fast your processor is, but entering a number then testing for all the divisions will take a while. Why not store a list of all the primes (up to the max number you can store in a variable) in an array or collection of some description. Then when a number is enter...
When a new HP Prime is powered up for the first time, it forces you to choose a certain number of parameters: The current time and date, your preferred language, number format and date format (unfortunately, proper ISO 8601 with hyphens isn't available). The language used to present you...
(lazy-seq(consd (primes-step(assoctable (*d d) (listd)) (incd)))] (primes-step{}2))) Usage is simply (take5(gen-primes)) Very late to the party, but I'll throw in an example, using Java BitSets: (defnsieve[n]"Returns a BitSet with bits set for each prime up to n"(le...
so I needed an algorithm for finding the next prime usingbase^lengththat was quick and efficient instead of hard-coding the primes. This allows for hash lengths far greater than anyone would want to hard-code for. For example, withbase62, you can produce a hash up to 171 digits before ...
