If the parameter value and tolerance have a common measurement unit, parenthesize the parameter value and tolerance and add a measurement unit after them, e.g., (34.5±12.6) ng/L. All variable symbols should be in italics.

There should be a 1/4 Chinese character spacing every three digits before and after the decimal point, e.g., 1 234.765 4, but which does not apply to serial number, year number, page number, numbered designation of a military unit, model number of instrument, and standard number.
