Sure.  I've got two sitting at home.  :)

FWIW, it used to be fairly common for process-control systems
to define operations only over the interval (-1,+1).  This made
implimentation easy, and the input and output devices
(temp/pressure sensors, valves, whatnot) all had pre-defined
ranges that mapped logically to the (-1,+1) interval.
