Preserved Topic: quick math help please. (Page 1 of 1)

well, im actually stuck at this. trying for an hour with no success...

say i have a variable from 0 to 100 that describes the probability. (or 0 to 1 if you like that)
depending on that i want a return value of true or false referring to the probability.


if this isnt understandable, maybe this example helps:

var x=68;

if (code here) {

execute something;

}


so, the if-statement should be executed with a probability of 0.68. understandable?

i am now searching for the code here part.

big thanks in advance.

edit: FYI: im doing this in actionscript.

Should be

if (Math.random() < x/100)

or
if (Math.round(100*(Math.random())) <= x)
following slime's



i don't really know what you want, hope that helped... i'm no *real* coder.... i did learn mathematica 4, but right now i'm studying atomic structures and can't really think about anything that doesnt involve 3.14159 in it, so spare me

cool guys!

thanks a lot!
