Hello PHP internals,
I've been running several million tests regarding the
arithmetically-random-functions.
The returning value at the end:
Avg: mt_r: 1073848211.4106 r: 16384.155746685 ~8016909
Avg: mt_r: 1073904131.0286 r: 16384.164383921 ~8503575
Avg: mt_r: 1074010520.4456 r: 16384.091213092 ~13136327
Shape:
Avg: mt_r: { avg of mt_rand() } r: { avg of rand() } ~ { value of $i (
iterations ) }
Means:
Average of mersenne twister in 8016909 it's is 1073848211.4106 (
corresponding to that in 8503575 it's the avg. is 1073904131.0286).
That's acceptable.
The rand(x) function alters the avg in 5M iterations really by just 0.1 ?
Wow, that's creepy.
Is there any way - to make it better ( or a bit as good as the m_twister is
? ) ?
Thanks,
--
