How to have "Random" return values in certain Range

Hello

Can anyone tell me how to make the random command return values in a predetermined range?

For instance,

"_x setDamage (random 0.2 to 1)" forEach ...

Thank you in advance.

randomValue = 
{
 private ["_min", "_max", "_temp"];
 _min = _this select 0;
 _max = _this select 0;
 // normalize
 _temp = random 1; 
 // map to the range
 _temp * (_max - _min) + _min
};

{_x setDammage ([0.2, 1] call randomValue)} forEach ...

{_x setDamage ((floor(random 5) + 1) / 5)} forEach units group player;

Does "predetermined" mean [.2, 5]?

I assumed he wanted to hit someone between 20% - 100% of their health which I why I used the / 5 in there, so it'll register 0.2, 0.4, 0.6, 0.8 or 1 as the possible results.

Your example was far more flexible unless he's looking for one these five results and a 0.37 wouldn't work for him for example.

Thank you both for your replies. These are very good answers.

Kylania, am I correct in guessing that

{_x setDamage ((floor(random 100) + 1) / 100)} forEach units group player;

will do the trick with decent accuracy?

Not to appear thick about it, but how would I go with applying the range 0 to 0.8? (@Kylania)

Well since the range is known why not:

{_x setDamage ((random 0.8)+0.2)} forEach units group player;

If you want 0 to 0.8 just use:

{_x setDamage (random 0.8)} forEach units group player;

Well since the range is known why not:

{_x setDamage ((random 0.8)+0.2)} forEach units group player;

That could return a number above the range limit of (.8). If the random number gen. returns anything above .6 then the end result will be out of range.

In his first post he says he wants 0.2 to 1. That's a difference of 0.8 starting at 0.2. I find a number up from 0-0.8 and add 0.2 to that resulting in a number from 0.2-1.0 like his first post.

The second example I gave was a response to:

Muzzleflash is perfectly correct :) it was the answer I was going to post.

range 0.2 - 1

((random 0.8) + 0.2)

range 0 - 0.8

(random 0.8)

range -5 - +5

((random 1) - 0.5)

range -10 - +50

((random 60) - 10)

etc.

Thank you all, this is perfect for my use. =)

range -5 - +5

((random 1) - 0.5)

range -0.5 - +0.5

((random 1) - 0.5)

or:

range -5 - +5

((random 10) - 5)
