Re: TIB: Randseed theory for 92+
Thank you all for your input. My theory is disproven. when the manual said
"factory defaults" i was hoping randseed 0 would be different for each calc,
but to no avail. As far as that pseudo-random algorithm, i don't think its
necessary to know it, so don't strain yourself. btw, i like those
scientific terms (i.e. "whacked out").
I think the manual uses 1147 because when they wrote the scripts, they typed
rand(5000) and got 1147, so they decided to use that in the manual's
examples. (I don't think this is true, but it sounded good)
