The |round=
parameter will round off the number to that many decimal places. It doesn't currently round the error margins; to omit these, use {{period span/brief}}.
If this template generates an expression error, it is because the period is missing from {{next period}} or {{period start}}. Please go ahead and add it in the appropriate place (once you've checked your spelling!).
You must also add the period to {{period start error}}, which contains the errors shown after the ± in the output of this template.
