def closest_index_in_range(lower, upper, step, value):
    '''
    Find the index of the closest value to `value` in the range
    [lower, lower + step, ..., upper - step, upper] in constant time. `upper`
    must be greater than `lower`. If `value` is outside the range, return the
    corresponding boundary index (0 or the last index). When two values are
    equally close, the index of the smaller is returned.
    
    For example, `closest_index_in_range(-5, 5, 0.5, -4.8)` will return 0, since
    -4.8 is closest to -5.
