I'm creating AB-tests and want to have a client side JavaScript function that returns a small integer. The integer will be the same every time the same user connects to my website. I don't want to use cookies, localStorage or IPs for this. Just a very simple hash with the user agent and maybe a few more variables.

We tested all convert to int functions with the dataset from agents.js, these are the results:
