Can someone help me understand why the randRange function below doesn't
return a random distribution, but the randRange2 function does?
Here's some test code.
thanks, - rajat
var a = [0,0,0,0,0];
var b = [0,0,0,0,0];
var x;
for (var i=0; i < 1000; i++) {
x = randRange(1,4);
a[x]++;
x = randRange2(1,4);
b[x]++;
}
trace ("a: " + a);
trace ("b: " + b);
// ----------------------------------------------
// Generate a random number in a range.
function randRange(min, max) {
var randomNum = Math.round(Math.random()*(max-min))+min;
return randomNum;
}
// Generate a random number in a range.
function randRange2(min, max) {
var randomNum = min + Math.floor(Math.random() * (max + 1 - min));
return randomNum;
}
