Re: [Bug-apl] RNG

[Juergen Sauermann]

Hi Xiao-Yong, in that case you may consider my earlier proposal of replacing /dev/urandom by your own RNG in written C/C++. You can provide the initial seed as command line argument to the RNG in order to make it reproducible. Also have a look at:       ⎕SYL[20 21;]  largest integer              9200000000000000000  smallest (negative) integer ¯9200000000000000000 which gives you the range of "safe" integers which are (most likely) not rounded to floats. Needless to say that "true" randomness and reproducibility are somewhat contradictory. /// Jürgen On 05/19/2016 12:35 AM, Xiao-Yong Jin wrote: We need reproducibility, so /dev/urandom isn’t an option. ⎕FIO is a wonderful thing in gnu apl. I still want something easy to manipulate in apl so I can play with different ideas easily.
