Ich habbe eine question for you regardings the: Randomly returning a number between a/from the range (from -> to), using the infomous Math.round()?

How is this achiveable in the controversial JavaScript scripting language supported by major number of Web-browsers?

"Herren und Mensch" is not a valid german salutation :) – schnaader Aug 08 '11 at 14:05 — schnaader, Aug 08 '11 at 14:05

That should return a random number between min and max:

function rangeRandom(min, max) {
    return min + Math.floor(Math.random() * (max - min));
}

from + Math.floor((to-from)*Math.random())

will give you a random number between from and to (not inclusive for to).
