UoM item behaves different than plain item for small values

[spacemanspiff2007]

There is a difference how small values are reported between plain number items and UoM number items:

Normal item

{
  "type": "ItemStateUpdatedEvent", 
  "topic": "openhab/items/NumGAChpjf/stateupdated", 
  "payload": {"type": "Decimal", "value": "0.000000000000000001"}
}

UoM item

{
  "type": "ItemStateUpdatedEvent",
  "topic": "openhab/items/NumHPTfdwy/stateupdated",
  "payload": {"type": "Quantity", "value": "1.0E-18 m"}
}

Maybe it makes sense to align this?
