random numbers

are the random numbers in turing even partly random, or maybe even different numbers every time. because im trying to get either 1 or 2 and its always coming as one. is there a way to easily seed it like in c++ so that i could actually get a random number or at least a different number every time. or would i have to create my own...

well the turth is nothing is random. in most languges it is an equation that uses the curent time as the seed to generate the random number.

in turing 3.x u had to put randomize b4 you used random comands to get better random numbers but i bivle in 4.x it adomaitclky calls it.

if u are having porblems u can uses randseed and randnext to chage the seed number that is used to make the random numbers.

if u realy whont to u can make your own code to find random numbers, i bivle i posted an example of how to make your own along time ago but i may be hard to find b/c i think it was in the help section.

code:

loop
var num, lower_number, higher_number : int
lower_number := 1
higher_number := 3
randint (num, lower_number, higher_number)
put num
delay (100)
end loop

THat should work (up)...

That's why you should learn Lisp which automatically changes its seed after every random number so that it will output a true random number Laughing

so you want a number between 1-2 and you want it to be different each time right?

thats not really random then, you have 2 numbers and you want the number to be diff each time, sounds pretty predicable to me

no i never said that, its just that for every single instance it is at 1, and i know how to use randint, thats what was not working. so i will just try to seed it. tahnks dan

u could just be very very very lucky or unlucky denpands on how u see it, lol.
