Just another question. I can trust on this random number ? The rule to it is
quite tested ?
I am thinking in implementing a function that return allways a random
number. What do you think of the trust of this function (random()) ?
My bigint field has 20,000 numbers and I'd like to make real random (used
like lottery).
Regards
Ezequias
