  An attribute of type Number Set. For example:

  <p>
  <code>"NS": ["42.2", "-19", "7.5", "3.14"]</code>

  Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and
  libraries. However, DynamoDB treats them as number type attributes for mathematical operations.
