Re: Random numbers: Ads may not include code that generates or uses random numbers. (Google)
var PseudoRandom = PseudoRandom || {};
PseudoRandom.seed = 12345 * (12345 + new Date().getMilliseconds());
PseudoRandom.random = function() {
this.seed = parseInt(("" + (12345 * this.seed)).substr(0, 13));
return parseFloat("0." + ("" + this.seed).split("").reverse().join(""));
};
// Example
for (var i = 0; i < 10; i++) {
document.write(PseudoRandom.random() + "<br />");
