module DatadogAPIClient::V1
  # Use the Arithmetic Processor to add a new attribute (without spaces or special characters
  # in the new attribute name) to a log with the result of the provided formula.
  # This enables you to remap different time attributes with different units into a single attribute,
  # or to compute operations on attributes within the same log.
  # 
  # The formula can use parentheses and the basic arithmetic operators `-`, `+`, `*`, `/`.
  # 
  # By default, the calculation is skipped if an attribute is missing.
  # Select “Replace missing attribute by 0” to automatically populate
  # missing attribute values with 0 to ensure that the calculation is done.
  # An attribute is missing if it is not found in the log attributes,
  # or if it cannot be converted to a number.
  # 
  # *Notes*:
  # 
  # - The operator `-` needs to be space split in the formula as it can also be contained in attribute names.
  # - If the target attribute already exists, it is overwritten by the result of the formula.
  # - Results are rounded up to the 9th decimal. For example, if the result of the formula is `0.1234567891`,
  #   the actual value stored for the attribute is `0.123456789`.
  # - If you need to scale a unit of measure,
  #   see [Scale Filter](https://docs.datadoghq.com/logs/log_configuration/parsing/?tab=filter#matcher-and-filter).
