Here's a good function header given the following:
I wrote the below code

    def _get_minimum_adjustment(adjustment, min_adjustment_step):
        if (min_adjustment_step and (min_adjustment_step > abs(adjustment))):
            adjustment = (min_adjustment_step if (adjustment > 0) else (- min_adjustment_step))
        return adjustment
    if (adjustment_type in (CHANGE_IN_CAPACITY, CFN_CHANGE_IN_CAPACITY)):
        new_capacity = (current + adjustment)
    elif (adjustment_type in (EXACT_CAPACITY, CFN_EXACT_CAPACITY)):
        new_capacity = adjustment
    else:
        delta = ((current * adjustment) / 100.0)
        if (math.fabs(delta) < 1.0):
            rounded = int((math.ceil(delta) if (delta > 0.0) else math.floor(delta)))
        else:
            rounded = int((math.floor(delta) if (delta > 0.0) else math.ceil(delta)))
        adjustment = _get_minimum_adjustment(rounded, min_adjustment_step)
        new_capacity = (current + adjustment)
    if (new_capacity > maximum):
        return maximum
    if (new_capacity < minimum):
        return minimum
    return new_capacity

What's a good function header?
