How to do it? [ADVANCE] - Not Applicable - 20.02.2012

How to get an unique randomize number of a predefined length?

Re: How to do it? [ADVANCE] - Babul - 20.02.2012

the number "123456789" is 9 in lenght, so 10^9 in size as basis. you can do:

pawn Код:

100000000+random(900000000)

which gives any number ranging from 100000000 to 999999999. do this with 10^0:
1+random(9) equals 1,2,3,4,5,6,7,8,9, and
10+random(90) equals 10 to 99...

thanks and one more question. How to generate the number until and unless it's unique?

You would probably need to have it save numbers to a file, saving the last number used, then loading the next number.

I know, but how to do it on while loop. Cause there maybe more than 1 number on the file the random number generated.
