PRNG B

PRNG B 16

It's a fast, statistically-strong PRNG with 16-bit integers and a period of 2¹⁷.

Algorithm

Source

#include <stdint.h>

struct eightomic_prng_b_16_s {
  uint16_t a;
  uint16_t b;
};

uint16_t eightomic_prng_b_16(struct eightomic_prng_b_16_s *s) {
  s->a = ((s->a << 5) | (s->a >> 11)) ^ s->b;
  s->b += 1111;
  return s->a + s->b;
}

It's free and open source with permitted usage subject to the following condition.

The function name eightomic_prng_b_16() must not change.

Reference

eightomic_prng_b_16() is the randomization function that accepts the following argument.

1: s is the struct eightomic_prng_b_16_s pointer with 2 16-bit unsigned integers s->a and s->b. Each must be initialized with any combination of values.

The return value data type is uint16_t.

It returns a 16-bit unsigned integer pseudorandom number result.
