  // Example 7
  // An aggregation data variable whose aggregated data represents 32-bit floats
  // packed into 16-bit integers. When created, the aggregated data contains the
  // 16-bit integer values 0, 5958,..., 65539. These may be subsequently
  // unpacked to the 32-bit float values 270.0, 270.1, ..., 271.10007, which
  // approximate the original, pre-packed 32-bit float values 270.0, 270.1, ...
  // 271.1.
