this gives consistent results accross 64 bit versions of J on windows (default Mersenne Twister)
? 10 $ 100 [ 9!:1 ] 79 233 122 99 45 95 82 5 12 75 0 88 21 does it also give the same result on 64bit android osx linux? On J6-32, there is a different result. I notice that 9!:44 structure appears to be: 2 (Mersenne T RNG; offset taken so far; 312 64 bit numbers or 624 32 bit numbers depending on J version. for 9!:45, it appears as though the length of the 3rd box must match 312 or 624. Also ?. provides different results in 32 vs 64 bits Is there a possible conversion for seed or state that will produce the same results on 32 and 64 bits? 624 = 312 * 2... perhaps there is some alternate memcopy procedure? tried _2*/\624 $ list of 32 bit numbers for 3rd box, but gives a domain error on 64 bits, even though it produces the right 312 shape. So it appears the state array must be less than 64 bit values. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
