ENG mode, n+1?

All HP (and other) calculators I know of, when set to SCI n or ENG n, will display n+1 significant digits of the result. So both SCI 4 and ENG 4 show five mantissa digits. The difference only is the decimal marker that in ENG mode is placed so that the exponent is a multiple of three.
