Answer 2

I have been trying but I the problem is making it 4 digit

Answer 3

num = '""+(1+Math.floor(9999*Math.random()));
while (num.length<4) num = "0"+num;
alert(num);

[edit]
:D
replaced "print" by "alert"... too many Python at same time as JS ^^

Answer 4

Your solution require little adaptation: only the most left digit cannot be 0 ;)

Answer 5

Yes :)

... but mine solution is more efficient, as it require only one call to random() for generating the number, rather four in yours ;P

Answer 6

Thx for all the solution guys I will try them

Answer 7

Yes, but you need this only for the most left digit, not the others ^^

Answer 8

Well you can tweak this when displaying the number.You could for instance check the length of the generated number. If it is a two digits number, you add two zeros before it. If it is a one digit, you add three zeros before... etc. that's how I personally see it.
