def cast_value(value)
  return value unless ::String === value

  # Because money output is formatted according to the locale, there are two
  # cases to consider (note the decimal separators):
  #  (1) $12,345,678.12
  #  (2) $12.345.678,12
  # Negative values are represented as follows:
  #  (3) -$2.55
  #  (4) ($2.55)
