Make accelerometer return integer value for a single axis?

How would I distill the input from the accelerometer into a value between 1 and -1?

It’s really just a matter of testing the sign of the axis and comparing against zero:-

if (Mathf.Abs(axis) < smallValue) {
  intAxisValue = 0;
} else {
  intAxisValue = Mathf.Sign(axis);
}

(Mathf.Sign treats zero as a positive number, in case you are wondering.)
