 * 0. Valid output range: min <= value <= max, and (value - min) is a multiple of step, or value equals min/max
 * 1. If max < min, direction up goes to min (max value), direction down goes to max (min value)
 * 2. If value is out of range or not on step boundary, round to nearest step in the direction and finish
 * 3. Otherwise, increment/decrement by step
