#include <boost/math/special_functions/prime.hpp>
namespace boost { namespace math { template <class Policy> constexpr std::uint32_t prime(unsigned n, const Policy& pol); constexpr std::uint32_t prime(unsigned n); static const unsigned max_prime = 10000; }} // namespaces
The function prime provides
fast table lookup to the first 10000 prime numbers (starting from 2 as the
zeroth prime: as 1 isn't terribly useful in practice). There are two function
signatures one of which takes an optional Policy
as the second parameter to control error handling.
The constant max_prime is
the largest value you can pass to prime
without incurring an error.
Passing a value greater than max_prime
results in a domain_error
being raised.
This function is constexpr only
if the compiler supports C++14 constexpr functions.
