Random Number - FreeSoul - 21.01.2012

How can I select a random number from let's say,1 to 100 ?
Thanks for the help

pawn Код:

new 
    number = random( 100 );

If you want to randomize between a minimal and a maximal number you can use randomex:

pawn Код:

stock randomex(min, max) 
{ 
    return random(max - min) + min; 
}

For example:
random(5) can return 0,1,2,3,4,5 while randomex(3,5) can return 3,4,5.

Nice Example [XST]O_x. Of course it's better way that the simplest because we can specify the numbers from..to..

Why would you use a stock for that? It's quite a lot slower than using a define.

pawn Код:

#define randomex(%1,%2) random(%1 - %2) + %2

Also, 1 - 100 can simply be done by

pawn Код:

new randomnum = random(100) + 1;
//Numbers start at 0 and would go to 99 but we added the +1 so it went from 1 -> 100.

This is also the equivalent to

pawn Код:

new rand = random(99+1);

No it isnt.
Your example would go from 0 to 98.

It's actually 0 - 99 because it's the same as just doing random(100).
