math.random()

Gives your script a random float, bounded below by `min` and above by `max`. The contract marks both bounds optional and offers nothing else. In particular there is no seed argument, so the language gives you no way to ask for a result you can reproduce. Keep the value out of anything a reader is meant to compare between runs. It is the one function in this namespace published in a single form, series. A series value is refused wherever a narrower form is required, so this result cannot fill a const, input or simple argument - a script's title, for instance.

                math.random(series float min, series float max) → series float
              

          //@lipi=2

noise = math.random(-1, 1)
plot(noise, title="Random Value", color=color.gray)
