----------------------------------- Michael Mon Oct 02, 2006 10:44 am randomizing even numbers only ----------------------------------- hey people how do i make it so that only even numbers are ouput when lets say i got ... loop randint (number,0,10) put number end loop i only want 2 4 6 8 10 i know i can use for i : 0..10 by 2 but i have to use randint ----------------------------------- Tony Mon Oct 02, 2006 11:41 am ----------------------------------- what happens when you take any number (even or odd) and multiply it by 2? :wink: ----------------------------------- ZeroPaladn Mon Oct 02, 2006 1:02 pm ----------------------------------- i was thinking of omitting any odd numbers using an if statement, but that works too. ----------------------------------- LaZ3R Mon Oct 02, 2006 2:19 pm ----------------------------------- Haha, michael, I'm telling the teacher your asking for help on here! :D Look up the "MOD" function... read it and you should be able to figure it out. :) ----------------------------------- As0k Mon Oct 02, 2006 2:37 pm ----------------------------------- also you could use a simple for loop instead ----------------------------------- NikG Mon Oct 02, 2006 3:44 pm ----------------------------------- As0k, read the last line in the first post. You've been presented with 3 solutions here: -Tony's clue (the best method imo) -ZP's if statements (not very efficient unless combines with...) -LaZ3R's suggestion of using mod ----------------------------------- md Mon Oct 02, 2006 4:44 pm ----------------------------------- As0k, read the last line in the first post.

The best solution is just to take your random number and multiply it by two. You'd want ot halve the range of yoru random generator to get the same final range of numbers though. ----------------------------------- Ultrahex Mon Oct 02, 2006 6:48 pm ----------------------------------- ok, since now you guys are that far, if you only want 0 to 10 or whatever, why dont you just make an array of those values that works also, maybe not as effective as you want though for flexibility later. ----------------------------------- zylum Mon Oct 02, 2006 10:54 pm ----------------------------------- or just listen to the people who know what theyre talking about and multipy by 2? ----------------------------------- ericfourfour Tue Oct 03, 2006 9:39 pm ----------------------------------- I remember having a similar assignment last year. It took me forever to figure it out but I got it by the end of class. The one's who say multiply by 2 are correct. Think about it. Is it just coincidence that even numbers are multiples of 2? ----------------------------------- r.3volved Tue Oct 03, 2006 10:29 pm ----------------------------------- The proper way to do this for sure is to half your maximum range and multiply the result by 2. If 0 (zero) is acceptable, then a range from 0-10 would be randint (number,0,5) number *= 2 //actually not sure if this operator is a valid turing operator Think about it... This will give you a range the range 0, 1, 2, 3, 4, 5 Multiply by 2 and you have the range 0, 2, 4, 6, 8, 10 It CAN be done other ways, but as far as Turing goes, this choice has the least amount of overhead, it's clean, it's easily readable and understandable and there's no logic issues Less calculations leaves less room for error and also allows for nicer code, and it's a lot less cryptic. I'm sure you're relatively noob as you're using turing, but once you have a strong foundation of datatypes and operations, you will probably realise that you've been overcomplicating a lot of code. (don't fret though, that's what programming is all about) There's never (some rare cases) a single perfect solution for any single problem. ----------------------------------- BenLi Wed Oct 04, 2006 5:58 pm ----------------------------------- or just listen to the people who know what theyre talking about and multipy by 2? agreed well it looks like the majority votes multiply by two...just do it ----------------------------------- NikG Wed Oct 04, 2006 6:52 pm ----------------------------------- As0k, read the last line in the first post.

The "You've" I was referring to is Michael, I guess I should've been more clear.
