IncludeMetadata

The objects/value endpoint supports the non-standard includeMetadata parameter in i3X.

This returns additional value metadata in the response to the value call, such as units-of-measurement, range, value-to-string mappings and suggested number of decimal places.

This option is only available for the value function and is not available in subscriptions.

It changes your returned values from this…

"value": "34.50252809821145",

to this…

"value": {
   "type": "decimal",
   "decimals": "1",
   "max": "100",
   "min": "0",
   "engUnit": "%",
   "value": "34.66807978850546"
},

This parameter can be combined with IncludeParents.
