“Ahl’s Simple Benchmark” from the magazine Creative Computing. The last result is the average of the earlier 10. Before that are 10 runs, because it speeds up when you run it a few times. I got accuracy 6.821210263296962e-13, random 12.58937371239872, time 00:00:00.92350 on my Numworks N0110 version 21.0.0. See https://en.wikipedia.org/wiki/Creative_Computing_Benchmark.
