public interface dist_rand

Version experimental

Generation of random integers with different kinds (Specification)

  • private function dist_rand_iint8(n) result(res)

    Random integer generation for various kinds result = [-2^k, 2^k - 1], k = 7, 15, 31, 63, depending on input kind Result will be operated by bitwise operators to generate desired integer and real pseudorandom numbers
