| * Test sketch based on rand-period-test.c by @unprovable | |
| * His sketch shown an anomaly with Arduino's PRNG, in which the LCG period seems to be unreliable. | |
| * Also the function seems to be quite slow; iterating over the stream until we get back to the beginning | |
| * takes 199340888ms (55.3724689 hours). It takes 1.5 minutes (approx) to generate 1M numbers. | |
| * So I decided to repeat the test with a textbook implementation of a standard LCG to see if we can get a | |
| * reliable generator with a stable period (and hopefully faster runtime) under the same conditions. |
