Double is not allowed on Datastore?

It looks like you are trying to save a double (decimal) into an ordered data store; you can only save integers (whole numbers) in an ordered data store. If your decimals only have a certain level of precision (4 decimals points for example), you can multiply the value you save by 10,000 and divide it by 10,00 when you retrieve it.
