RANDOM

[DaVIdoSS]

Could someone please show me how this work:

_rndnum = round (random 3) + 4;

This returns 1+4=5 , 2+4=6, 3+4=7  ?? 

and that:

_rndnum = floor(random 7);

This returns 1,2,3,4,5,6  ??

 

Is that right?

 

I try to search about my self but idk even how i should call it.

You can find info here: 

 

round => https://community.bistudio.com/wiki/round

floor => https://community.bistudio.com/wiki/floor

 

like in math, the content in the (parenthesis) is taken separately, so the result of Random is generated, and you either do the rounding or the floor in that give n number. 

Your first example of the round(random 3) is correct, the result will be that.

_rndnum = round (random 3) + 4;

could also return 0+4=5

_rndnum = floor(random 7);

could return 0,1,2,3,4,5,6

Dunno exactly, but isnt floor(random 3) not like 0,1,2?

Yes, because random x returns a floating point number from 0 (inclusive) to x (not inclusive)

(random 3) might return 2.99999 but never 3
